ProblemEdit
Oblivion crashes after exiting the sewer, the exit of the starter dungeon.
Cause - Non-Existent RaceEdit
It could be the case that mod is trying to modify a non-existent race.
Solution: Try deactivating race-changing mods.
Cause - Weak HardwareEdit
This can be caused by a low end or unsupported graphics card. See System Requirements.
Solution: Get a better video card or a machine that is better for gaming.
Cause - A BSA cannot be foundEdit
Oblivion is looking for resources that do not exist. A common example is when a user installs "Martigen Monster Mod" (MMM) without renaming the BSA.
Solution: Make sure all BSAs are either loaded with a plugin or registered in the Oblivion.ini. (See Loading BSAs for more information.)
