oblivion doesn't want to start. i get the screen in the very beginning where they show bethesda on a black background and then it shuts down. it is always after i instal oblivion modd manager. anyone knows what i should do about it ?

OBMM should not do that. Will the game run if you uninstall it?

no i doesn't run anymore if i uninstal it, but it happened after i installed OBMM.

Try doing a thorough reinstall of the game. http://www.gamesas.com/bgsforums/index.php?showtopic=561101&st=0&p=8103714&#entry8103714.

ok i hope it'll help

edit:

i deactivated all my modds and now it works again, so it has to be a problem between some mods/

Get http://www.tesnexus.com/downloads/file.php?id=20516, and run it on your load order. May also want to get http://www.tesnexus.com/downloads/file.php?id=22368, as it will tell you if you have a missing master. (which sounds like exactly what the problem is.

Which means you're missing an esm file for an esp that needs it (i.e. Mart's Monster Mod.esm for Mart's Monster Mod.esp, for example). So check your mod installs. The esp will be red in Wrye Bash if the esm is missing.

that ain't the problem i think. i unistalled obmm. i uninstalled oblivion, reinstalled oblivion and then i added all my modds just to the data page and then activated them in the data folder when you start up oblivion. then i start oblivion and it works. without using any of those programms like boss, wrye bash, obmm. it is always when i have installed obmm. then the problems start.

Can you install Wrye bash, and still have the game work? If so, might be better to just blow off OBMM. Use bain installers instead.
