I just downloaded the trial version of Vegas Pro 15 and for some reason whenever I press a button more than twice (space bar) or attempt to play the video then pause it the whole program becomes unresponsive and I'm forced to close it. I've got a core i7 CPU, Nvidia graphics card, and 12 Gb of RAM. This only happens when the program is running several files already like the test animation that comes up when you first install it. It couldn't even run that. I'm just lost at this point cause if I were to buy such an expensive software I wouldn't expect it to behave like crap and be totally useless.
