Marmoset not starting up correctly

[XcapeArtix]

Hi all, I've been beating my head over this all morning. I wanted to check out Marmoset, so I downloaded the Trail Version. When I open it and click on "Trail Version", a new window opens up. It is a blank white window called SDL_app. I can't do anything with it, not even close it, and have to shut down to get rid of it.

Has anyone else run into this issue or know how to fix it? I have more than enough computer power to handle the program and using ATI Radeon HD4850.

Thanks for any help!

When i was having problems running MTB i updated my graphics card drivers to the latest ones and it worked fine, try that?
