I have inputted my flightplan on battery into the left CDU. After I got AC power running I have saved the route then tried to load it on the right CDU generating a weird CTD where X-plane initially crashed then displayed a blank window unit I have killed it manually in the task manager. The route was EGPH to LOWI if that helps anybody. Logs attached! CL650_Log.txt Log.txt

Title says it all, when I enter -55 as ISA dev into page 2 of the PERF INIT page on the FMC, I get a CTD. Logs included. CL650_Log.txtLog.txt

For me it leaves no log files at all. The xplane folder doesnt even have a Log.txt, and the challenger log folder is empty. Tbh this is the most interesting thing about the whole situation. Is there an external logging tool I could use? If I post a video about the crash, does it help?

For example, when I try to click the computer at the flight planning station, click visit Navigraph in the settings, or when the plane tries to connect by itself to the Navigraph, the game first freezes up, and about 2 seconds later, it just deletes the X-plane executable. Windows Defender is off, no other antivirus software is installed. The whole event leaves no logs, there is nothing to be found in the usual place for the logs. Afterwards, I have to run repair (running steam version of XP), and all my settings and preferences are lost. I cannot offer anything else, I have reinstalled all my drivers (Chipset/CPU/GPU/Soundcard/BIOS) and also Xplane and the Challenger itself. Nothing helps, and I'm getting really frustrated right now, I would appreciate any help.
