Sounds as if you need to format the device. Go to the Menu - to Submenu press Ok - go to Format press Ok - Click start -

This will permanently erase all data and reset the memory so you will have the maximum amount of recording time again.

Unfortunately, this item does not contain a Serial Number. These items were produced with Model Numbers only. You can access the system information by selecting sub-menus within the device. If you do not know how to do that, I can provide you with a detailed Operators Manual. Please send me and email and I will attach the manual for you. [email protected] Lawrence Brown

Yes, the files are likely corrupted. You can try a file recovery program such as PC Inspector Smart Recovery. Search snapfiles.com for a free download.

You must first make sure that the files are indeed good. Install VLC (which doesn't needs external codecs)
and try to play the wma files with it. If it fails then the files are corrupted. If it works then either the codec pack has been removed - reinstall it from
or the files were coded in a format Easywma can't support - like the lossless and voice one, or with DRM. If it's the last case then configure the recorders accordingly.

I've been having the same problem recently. It seems it might be low battery power. When I turned my recorder on, the battery was showing three bars, then down to two, but one would think it should still function with two bars.

However, before I went to buy a new recorder I decided to put a new battery in. So far it has not messed up again with the new battery. I'm pleased because I've used the heck out of my recorder and LOVE it...don't want to have to buy a new one.

It should be on the side of the recorder,visible after you remove the battery or it may be on a decal on the back of it

Have you tried rebooting your pc and do you have admin privleges if your running vist or 7?
Also make sure you put a fresh battery in the recorder,allow it to boot up and settle.Then separate the recorder,make sure the hold switch is not on hold and see if your pc recognizes it as a drive under my computer

good day, you might want to try this link for you to update you windows and hopefully the error code will be gone. hope this helps, have a nice day

The recorder should be formatted using only by using the internal FORMAT function found in the recorder's Menu. Formatting using the computer may corrupt system files needed to run the recorder, so computer formatting is not recommended. Individual files can be deleted using the computer with no negative effects.
The only thing is send unit to service
