Game Mode Not working

[Thiole]

When i origionally installed, The casting worked in League of Legends fine. Next day, i restarted, didnt close procaster, and it didnt work next time i tried to stream LoL. I restarted Procaster as Administrator and it failed to work. I tried on other games such as Quake Live and BfBC2 and it also failed to work, tried reinstalling it ( uninstalled and reinstalled completly, then ran as admin and failed to work again. So what must i do to get it to work. AND YES IM IN THE GAME AND ITS ON GAME MODE WHEN IT TRIES TO STREAM, desktop mode works

nothing changed from when i first ran it to recently except a few reinstalls but without the reinstall it didnt work ( w/ or w/o running as admin) (vista)
