I have been running into this error as well recently. I've already changed bAllowMultipleMasterLoads to 1 and have saved the file to Read Only, but when I go to load up the files for the mod that I am working on it comes up with the message that it is unable to load multiple master files and aborts. I have noticed that when I first start up the NV:GECK that it has all of the master files already selected excetp for the main one and any mods that I have. Looking for a solution has directed me to this thread, as well as others that offer the same information. I've updated the GECK recently, and now am at a loss as to what to do since the solutions that I have tried have not worked. If anyone has any other advice, I would be thankful.
