Sony Vegas 12 unusual bug!

[peacezeza1]

I dont really know how to describe it,I try to restart my computer already, I tried to google online already and no one really have the problem like me,after 12 hours of work on this project this...happens Https/www.youtube.com/watch?v=CFThCnRNdcU&feature=youtu.be
By the way, Im not sure that It's a display box or "Media offline" bug, it's the video bug, I rendered it already and it appears that even I render it out its still black.
Please help! Its due on Friday! Would very appreciate help!!

I googled also and found

1. Disable sample
or
2. Uncheck Render Looped Region Only

Try one of them, but most likely number 2.

Try turning off GPU rendering.
