Why are you doing things your own way? We're here to help. There was no reason to buy another copy of X-Plane. There is something going on in your add ons that is causing a conflict somewhere. Our job is to figure out what that is.
Contact Steam and ask them to refund your 2nd purchase of X-Plane. If you also purchased a second copy of the TBM, you'll need to contact X-Aviation to get a refund.
If you want to get this fixed, you'll need to work with us on this. Please do not try to diagnose this problem on your own. There is a procedure to all this.
If you're interested in continuing to find a solution, let me know. I'll forward your log files to Saso, and get him to take a look also.
