Ok, I fixed my former mod problem and another problem just arose. I can't start up oblivion. When I click play it starts to pop up and then it goes back to my desktop and doesn't start up. Please help me!

Likely a mod conflict. Try rearranging your mods and disabling some.

ok Thanks!

if no error message comes up and the game just closes very suddenly everytime you try to start the game up, then it sounds like something simular to having a mod loading before another mod that it relies on. If you don't already have a mod manager, then you should download one so you can get mods to load in the right order

But it could be just a conflict though like shadow said

It will also do this if there is a mod that needs OBSE trying to load and OBSE is not running. . OBSE must be started before starting Oblivion. Use the OBSE launcher or OBMM to launch Oblivion if you need to run OBSE.
