Hey everyone, some help would be appreciated. My problem When I try to start oblivion (with either OBSE launcher or regular launch icon) the game crashes. Since these problems began I've only been able to start Oblivion 2 times, which is strange, cause nothing had changed with the times the game crashed. Generally nothing happens and the crash is immediate. Only when I've freshly restarted my PC and launch Oblivion, I for a few seconds get to the see the "Beth-soft Zenimax" movie and then BOOM crash. Game-version I'm running the latest Oblivion version with Knights of the Nine and Shiv. Isles, with the required "unofficial patches". Mods? I have a lot, really a lot. But the build was fine. Most mods are simply extra armours or weapons. The really influential mods are: - OOO - xUL (I think cause it visibly alters a lot of the world - OBMM Recently I added a few new mods, the biggest being: - Enhanced Economy - OBSE (cause it was required for the above) So far everything still works fine as ever, no problems, no crashes whatsoever. When it went wrong Then I installed the fine looking mod "CM fireflies combined companions" and to fully use it I also installed - as recommended by it - Enhanced Daedric Invasion, caslte Hoarfrost, Castle Dunkerlore and 2 more mods by Firefly. I start Oblivion... everything works. Now I go to sleep, next day I'm thinking, time to play a bit more... and the game crashes. What I don't understand is why? The mods at first worked fine, no significant problems whatsoever etc. So I'm at a totall loss as to what is wrong, moreover, turning of the last installed mods didn't change anything, the game still proved unable to start. The problem has proven to be recurrent and I really don't know what to do... Can anyone tell me what is wrong here? Thx
