its terrible, I changed from ppp 5.5 to cs6 via cloud , and it does not at all run as it should. and I changed projects to cs6 and can not go back now. I can not work like that, tried everything. deinstalled, reinstalled, changed discs, cleared all caches etc. no change, playback almost not working at all, and if running it stops after 10 secs. no preview of any transitions, very slow working. when pushing "play" it takes up to 25 secs, then stops after 6!!!, is there a solution, or can I get back my cs 5.5?
