Yea I didn't have that, now I do in my oblivion folder. same CTD though, even if I try to run obse loader.exe through MO. I'm no expert but pretty sure Oblivion and OBSE work through steam with the obse_steam_loader.dll found in all recent versions of OBSE. The purpose of the "obse loader.exe" confuses me. I know originally it was only for retail version Oblivion and you could start the game with it to use OBSE. Later on someone developed a better one that you could apparently use with steam (though i wasnt modding at the time so I did not try it out). But if I try to run your obse loader.exe from my oblivion folder it just makes the "you gotta run Oblivion through steam" message. Otherwise no easily noticed effects.
