Game streaming stops just after starting

[bigDean636]

Hi there. I'm running Windows 7 x64 and I'm trying to use the Procaster to stream my World of Warcraft arena matches for my friends. For some reason when I start it up, I get the green buttons in the top-left corner, but when I Ctrl + F1 to start it, it acts like it is starting but then stops. I'm not sure what's going on.

Thanks in advance for any help!
