I recently tried some mods, and it skrewed up my game, it wont open properly, so i tried going back to normal, uninstalling the obmm thingy and deleting the mod files, but it still messed up, im running on Windows 7 and tried the alternate starts mod, the dark UI thingy with 2 combined other ones, and the XP changy thingy... please help, if im missing something or can fix it please let me know, the site I went to try and get the mods wasnt safe either, almost got hit with a virus, but i shut my CPU off from the powerbar before they can do anything.

Mods that change the interface make changes, add or remove the ini files that control the interface. Those mods if not installed correctly can cause all kinds of problems. The simplest way to fix it would be to uninstall the game and delete the oblivion folder (saves are stored in My Documents so don't worry about those). Also on my windows 7 computer I didn't install to program files because it caused problems for me (I installed it to c:\games)
Hope that helps.

Where did you get your mods? Most people get them from the TESNexus

TesNexus, TESAlliance and Planet Elder Scrolls are all reliable sites so long as you follow normal precautions. Planet Elder Scrolls IS free as well, you just have to find a discreet registration button.

You should read the http://cs.elderscrolls.com/constwiki/index.php/Oblivion_Mods_FAQ faq before modding your game. The stickied threads in this forum provide links to more download sites and modding tutorials.
