Every version of NMM which inludes BOSS doesn't want to disable Skyrim 'update.esm'. It causes everytime gamecrashes. File validation gives no result. I've also noticed this bug almost since Skyrim launch when tried to enable the "Update.esm" through NMM. After such enabling all objects in the game (game menu) became covered with a single color (earlier it was purple and now it is red) and the loading of the savegames craches all the time. The only way out for me now is to use the old 0.14.2 version of NMM which lets to turn the "Update.esm" off. Maybe there is some particular load index of the "Update.esm" to be loaded right? Hey, I've reported about that 2 weeks ago! Is it so hard to fix just one option!? Excuse me for the incontinence, but I just can't play and waiting for the repair. If somebody knows something about this bug, please response!
