I recently installed the Gates to Aaesgard mod from oblvion nexus, and now whenever I try to start the game, it will go to the first black screen when the window opens, then close. Whenever I try to click uninstall on the launcher, it tells me "The oblivion launcher could not find the uninstall program. Run the setup.exe on the oblivion install disc to uninstall."

I've uninstalled the GTA mod, and I cannot uninstall the game via my programs list either. What the hell.
