Vegas Movie Studio HD Platinum Version 11 (Build 322). I bought this new when it first came out. I have successfully rendered video up to 5 hours in the past. Same PC. But all of the sudden, VMS stopped rendering. I'm working with a file under 2 hours and I continually get a memory or codec error. Windows 10 Home (64), Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz   3.40 GHz, 16GB RAM, AMD Radeon HD 7700.
