We're trying to deal with the 11.31 problem at the moment. That problem is a blanket issue for, literally, everyone who updated to 11.31. This one is an isolated case, limited to a few people.
I'll get to it as soon as I can, but first thing I'll need is a log.txt file. Not the TBM900 log file, but the one found in your root x-plane folder.
You could also try, if possible, installing a complete bare installation of x-plane somewhere on another hard drive. No scenery, and installing the TBM in that and see if the problem persists. To me it looks like you have missing G1000 files.
