I also have same problem last night and am yet to get over this. I newly installed Boris fx BCC8 trial version on my system. After working with the flicker fix and particles. I realized that each time I tried rendering and exporting,it will suddenly stop my CS6 from working. It repeatedly does that many times. Pls help. I run on 64bit dell XPS 8500. My CS6 has been working perfectly before now,please help fast,10days is left for the trial period and I want to be able to test this trial version successfully to decide whether to buy the full version. Thanks
