Sony Vegas Render problems

I recently got a trail ver. of Sony Vegas 12, and whenever I render/screen shot a video, a watermark in the corners always presents itself. I've never had this problem before. Does anyone know how/if I can fix this?
I have two contest videos to render, and I have a massive problem with watermarks, so I don't wanna render it and upload it with it on :/

This is what it looks like from a screen cap:

I read somewhere that it doesn't show up when exported as .wmv but other than that is just seems that sony is putting watermarks on their trials from now on as the full version doesn't have it.
Sorry I can't be of more help, vegas 12 is new and there isn't much research to go on.
