I'm running Catalyst 3.326 and my G5 just crashed and has been replaced by a new iMac. I know I should upgrade to v4 but my fixture library on my Hog3 is not updated to accept v4. I have a couple glitches, wrong file or file not read on layer cue, and it only recognizes the iSight camera as a video input. Is this because of Snow Leopard? Any suggestions?
