I started having CTD issues with FSX all of sudden so I deleted the fsx.cfg file to have fsx rebuild it.  I have multiple add on sceneries including GSX.  FSUIPC is also installed.  Typically my add on bar has about 10 options and all it shows is AI ships.  My have FSDREAMTEAM KJFK and it loads up a few of the add on jetways but all the buildings are missing and I have no ai traffic.  Something very large has gone wrong.  I have Mytraffic X 5.4b.  Am I going to have to manually uninstall all my scenery and add ons and reinstall them?  I have 8 profiles in FSUIPC, hopefully I don't have to re do all those as well.  That would pretty much be a fresh reinstall without acutally uninstalling fsx!  Can somone please help me!?

Did you make any changes to your DLL.xml or EXE.xml file(s)?

 

The FSX.cfg file would just hold "trusted entries" that upon start-up would load. After renaming (not deleting!) the FSX.cfg file you should be prompted to run an add on or not. Then you would be asked if you wanted to trust the entry, where you would have no more prompts at start-up.

 

If you aren't getting asked for anything, such as FSUIPC, then I'd investigate a problem with either of the two files mentioned above, or maybe both?

For the traffic portion:

1. Make sure you see SimObjectPaths.6=MyTraffic\Aircraft (that 6 might be something else for you) in your FSX.cfg

2. Add the MyTraffic folder to your FSX scenery library

I didn't touch the exe or dll. Will I have to uninstall everything?

You won't lose any of your FSUIPC profiles if you make a copy of FSUIPC.ini in the modules folder.  There should be a backup of your dll.xml where the fsx.cfg is, open it and compare it to the one that is being currently used.  Have you recently upgraded FSUIPC by any chance?
