How do i get the wma enable system of of my psp

Yeah its like that because you aren't saving your settings. 
I would say get a music convertor and convert your wma files to mp3 from mininova.org
OR
Save your psp setttings.

you need a wifi connection to activate it , or if you have a cfw , go into recovery, go to regsitry hacks and then you can enable them from there just by pressing X , there is good instructions at you tube. i googled it .

Yes you can play wma files on psp but you have to change a setting first.
1.Go to settings then scroll down to system settings.
2.Hit x then scroll down to enable wma playback then hit x again.
3.Follow steps then download music to music folder on psp.

You need to make sure the music files are otherwise MP3 files, or WMA files and are in the Ms0(Memory card):/PSP/MUSIC folder.

how do i turn on the wma playback

Do you have the newest software on the psp?
If you do go to The PSP Home Page
Go To Settings
Go To System Settings
Go To Enable WMA Playback

First you connect to a pc, then go to the folder labeled psp...find a folder called music and paste in there. or just create a folder in the psp folder called music and again, paste the songs in there. If you want to listen to music, you have to enable wma play back found in system settings in the psp, but you have to have a wireless network to download the wma download(that is just if you didn't know). I hope that this helped!

what ever you do, DO NOT RESET SETTINGS cause then you just have to reset them and it wont do you any good. I had the same problem. The most lodgicall way to solve this is just to spend like 3 bucks at mcdonalds and get the wifi so you can play online multiplayer, go on the internet, and fix the wma feature. Or you could just free load off of a friends wifi or wirless setup. But you may have to enter a security code.

conect ur psp thru usb and go to my computer and click removal disk and psp and make a file in the psp called MUSIC and put the songs in the file called MUSIC and it will work

First of all, an aoss button is for wireless play. As for the wma songs, they need to be converted to mp3 format for better quality and to work.
