Take a look under the point "other Problems", there's a number of possible reasons&solutions.
Aside from this...if you ask for help with a technical problem you should at least add your system spec., it's allways guessing but without information it's only fortune-telling.
right, should put that in mind
but also i managed to fix the game, by removeing the launcher and rename the game itself into the launcher name, so oblivion.exe would be oblivionlauncher.exe adn there for i start the game direcly and not thro the launcher, dident work with just starting the .exe file from the locasion that i installed the game in and only work thro gog
what the problem was i dont fully know as the game just dident want to start at all, have dis problem for ALOT of old games of mine for example battle of middle earth 2 and postal 2
but i resolved atleast dis problem, thanks for the help anyway!
