The code 39 problem

Hi I'm tita and I'm having the exact problem and I tried what you had down except when it came to looking for a folder that had DVD CD DRIVE CLASS and so on. I didn't see a folder with that on it. I have Windows Vista. Does that make a difference. I don't know where else to look. Thank you. I found this site by despertly looking for a solution. Tita, from San Jose, CA

6) After deleting the keys, close the Registry Editor

7) Reboot your computer

8) Open My Computer and check to see if your CD or DVD drives have returned. You may also want to open Device Manager and verify that the yellow exclamation and error code on the CD or DVD drive is gone.

I transferred a couple mp3's to my NWZ-E344 that were write-protected (marked read-only). Now I can't delete them from the player. I tried several ways, WMP, opening from My Computer, and...

"Write Protection" is a definate problem, but may be solvable (short of reformating) by checking the original files which, most likely, came from a CD copy. To see the attributes, right click on the icon and go down to select properties. There you will find "read only" highlighted for both the album folder and its sub files or songs. At this point the trick of avoiding "write protection" is to select the "read" attribute to unselect "read". Then select "Apply" and a window pops up showing boxes, one of which will say apply to folders, sub-folders or files, etc. Click on that box, then click on "OK". You will notice that the folder "read" attribute will remain highlighted, but that the subfolders' attributes do not!! (This is for Windows XP) At this point proceed to copy this folder OVER the same folder. You will be asked if you want to overwrite the existing folder with the same name. YES, please. The files will be replaced with identical file data, except the "read" attribute will be blank or unhighlighted, and NOW you can delete the folder.

This is a Java (OS) error and is usually caused by a application or possibly a file that is corrupted. Lets start with the easy stuff and see if we can get this corrected.

Try this first in this EXACT order!

Remove the battery from the phone and wait 20 seconds, then, with the battery still out, plug it into your wall charger, then place the battery back in and turn the phone back on.

You do that by downloading the Blackberry Desktop software if you don't already have it (see link below.) Then plug in your Blackberry, open up the software and go to "Device" and then down to "update my device." and see if there is a update available.

In case, if that would not help, you need to get the new phone. You could also call Verizon and see, if there is any recent update for your phone.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

I have forgot my sercuity code that locks my apps can you help

Try connecting it to a computer. from there you can open the folder then left click. when the drop menu comes down click properties. you should find a box that says "show hidden files". Once that happens look around for security and delete the passcode folder. I'm not sure of the make of your phone so this may or may not work

The all programs is blank after the system is infected, has windows xp. already run superantispyware, hijack and dial a fix . now the infection is not popping up, but teh all programs is blank except for...

Well, can you still access the programs from the Start Menu or from the icon/s on your Desktop? If so, folders inside the "All Programs" folder might have been hidden by the virus/es. This is very common and sometimes, they couldn't be unhidden, but you will be able to run the program without any problem after the virus/es is/are removed or cleaned. First try this step, open "Control Panel", double-click "Folder Options" and when the Folder Options dialog box is, click the "View" tab, scroll down and select the "Show Hidden Files" radio button, again scroll down and uncheck the "Hide Protected Operating System Files (Recommended)", click "Apply" and then "Ok", now go to All Programs folder and check whether programs folders are shown or not.
Here are few tips I've posted regarding this issue [click HERE and HERE.]

Let me know if you need further help.
Good Luck.

Missil A940LCD2PK mp3 player turning off

I don't know if mine is a Missil brand, but the pix of the Missil A940LCD2PK look exactly like my no-name Chinese MP3 clip-on player. I am experiencing exactly the same problem. My firmware is 2208/06/12 V1.05. Everything else works as it should except, of course, music mode. The directory has "root" and a single "voice" folder for voice recordings. Is music mode looking for a folder? Is there some way to correct or upgrade firmware?
