Hello, i just bought oblivon and soon as i startup the launcher and click play a black box pops up on the left and after a few seconds

i get a popup saying: oblivon stopped responding. and it searches for a solution and it cant find one. and then it closes.

i am running windows vista home premium 32-bit

these fixes are the ones i tried:

re-installing it, rebooting laptop, deleting oblivion.ini.

anyone knows a solution???
