Yesterday, for some reason, I got this uncaught exception error (See attachment). Now my bb is unable to play audio and video files. I have restored it to a previous date and even reloaded the os, but it hasn't helped. Any suggestions?
You might want to copy the files from the card to your computer. Format the card and restore the files. But if one of those files are corrupt, the error might just return.
You might want to also try searching the card for bbthumb.dat files and erasing them. They are an index to media files and if it got blasted, it could cause problems.
lol, if you backed up your BB and then reloaded the OS and then RESTORED the backup (which was made AFTER this problem happened), chances are good the cause is WITHIN the backup of the databases themselves. Run a backup of the BB and once that's done, just do a Security Wipe of the phone. Then test media playback BEFORE you restore the backup. If it works, you'll need to do a selective restore of just your messages, contacts, calendar, memos, but none of the "functional" databases that control other factors.
If the media playback still doesn't work after a Security Wipe, then you have an OS corruption and you most likely DIDN'T reload the OS as you say... or at least didn't reload it correctly for some reason. I can't say what those reasons are without knowing exactly what steps you took to do it.
