I'm running CS6 Premier off the Cloud and am running into serious freeze up with no rendering available with the warning "Unknown Problem". I'm running a Mac Pro with 10.6.8 and a Nivdia GeForce 285 card with the latest driver. Premier 5.5 never gave me a problem. Also the CS6 tells me that the Virtual Discs are not available. It asks me to say OK to placing them in the Documents Folder, and I say yes because there's 14 Gb of space free on the HD. I'm running files off of a LaCie eSata 3 Gb link in Raid which has never given me a problem. Got any ideas what's happening? Or is CS6 just so much more faster than 5.5 because it eats up my computer and I need a new video card? I'm running a MacPro with a 6-core Intel Xeon at 3,33 GHz and I've got 24 Gb Ram. Any advice welcome!
