can't play mp4 videos
 

I use BSplayer 2.63 and windows7.

I had a message from BS that a codec is needed in order to play a video and I did the istallation. I don't remember the name of the codec, but since then I can't play mp4 videos because BS reads them as sound files.

I have unistalled and install the programm many times but the problem stays.

Also, when I open BSplayer I see this error: "can't save configuration file! please reinstall with default settings or choose folder with write permission."

:confused:

This is a Window 7's problem. You don't have full acces as a user on that computer, so the folder in which BSPlayer try to save the codecs and the configuration file is read-only. Try to disable UAC and un-set Program files folder as read-only.

I did it, but it didn't work.
Also, it's asking me to change my manager to EVR, but my manager already is EVR.

It keeps asking you that because BSPlayer can't save the configuration file. You still have folders in which you are not able to write.
Have you disabled UAC and restart ?

Yes, I did everything you said.
I used BSplayer without problems for about 6 months until that. I can't find more information to give you...
Something that seems wrong is that video properties appear with gray colour.
