Strange behavior. I installed Demo version of Vegas Pro v14, with 30 days extended trial. All works great. Today when starting Vegas Pro 14, I got a pop-up from MAGIX that is buy upgrade for $199.00. I purchased upgrade at $199.00. Vegas Pro v14 works great till I render and quit (File --> Exit) Vegas. I get Kernel fault.
BTW: My laptop is Acer V17N, with Intel Skylake, 32 GB RAM and Nvidia 960M with 8 GB vid RAM, 1TB Internal SSD and a second 1TB HHD, 4K UHD display.
