I'm trying to play Oblivion on PC but can't seem to get my character to level. The red bar at the bottom of the character screen never moves. I've been playing for hours and my skills level up as they should but I'm still at level 1. I recently installed the game on a new computer that runs Windows 10 when this issue began. My other computer also runs Windows 10 but the game works fine on it. The leveling bar moves as it should and I level up. I've tried uninstalling and reinstalling, using a digital version instead of a disk, and tried all the possible compatibility settings but no joy on anything I've tried. I am not using any mods or anything that would change the game in any way.

Is this a problem that anyone has had before?

Search after search at multiple sites using multiple search engines has revealed no solution. I've only found 2 other people who have this problem so it seems to be computer specific and neither of them seems to have found a solution.
