So, after using an OOO/MMM setup for awhile, I thought I'd upgrade to FCOM, to get the full package. I proceeded to do a clean reinstall, and followed all the instructions to the letter. However, I'm getting a crash before I even get to the menu. I checked with the FCOM expanded load order page, and can't find anything wrong there, but I thought I'd see if you folks can see something I'm missing/doing wrong.

(Also, Wrye Bash is awesome. I don't know how I got along without it before!)

Usually means missing master if you can't get to the menu.

In Wrye Bash files with missing master should have a red colored icon if I'm not mistaken, do you have any of those?

The only one that lists a missing master is Cobl Filter Late MERGE ONLY, which I merged into the bashed patch.

Try deleting Oblivion.ini in My Documents/My Games/Oblivion and let the game generate a new one on startup. Also, Cobl Races TNR.esp and Cobl Races TNR SI.esp should be imported into the Bashed Patch (Import NPC Faces) and kept unchecked - plus you don't need MMM-Cobl.

Thanks for the help, that fixed the crash completely for me.
