For some reason when I got After Effects CS4 on my 32 bit computer, everything was working fine. Then for some reason when I put (now) music into my music composition and I play the music (or render preview), it says "Unable to create drawing surface".
But that's not the only thing. When I go to the other composition where I put my music composition, I press on l twice, it show no wave form but when i go back to the original music (in the music composition) and i press l twice, it shows!
Even when I press on preview, there is no music happening! I don't know if it has to do with the Key-frame Assistant on the audio in the music composition when I converted the original music into it.
P.S. I did search online for help but the only suggestion was to disable or turn off OpenGL but I'm not sure if I have it and I don't know how to turn it off.
