I love vegas but been having issues.

My main Concerns are

1: its not Nearly optimize as 14. Video files i used on old projects or edits of older projects that was edit with 14 runs very laggy on 15

2: which a really big issue. I can seen video in preveiw window but when its full screen.. screen turns black.

I tried not to prirate vegas becuase i love this app but makes me wish i did before paying 800 for it..

Anyways if anyone knows amy fixes i am down to try.. what i tried so far was turning off muti core rendering i belive.. updated windows updated gpu.
