I don't have a clue whats going on here....Maybe you remember I'm one of the handfull guys wich have CTDs with the J41 when exiting etc.But during flight everything is ok, I haven't had a single CTD with the J41I was flying too yesterday and had a nice flight.I have not installed anything.I wanted to start up FSX today and got a new kind of message:translation: "FS has encountered a problem with some software...[...] Would you like to execute this software"pressing "yes" results in this message and termination of FSXI have uninstalled the J41 - no successI have uninstalled the MD-11, too and deleted every PMDG stuff on my computer - success!!Installing the J41 again and FSX starts as normal.Haven't tried now to reinstall the MD-11 again, hope this works, too.btw: this procedure haven't any effect for the CTDs. With the reinstalling the CTDs are as present as before!!!Maybe you noticed my "modifications" of the [cameradefinitions]. i don't think so, but could this error be related to the new camera definitions?I have restarted FSX yesterday often without any error....Pleeeeease :( I know you do your best to give support... but it's a little bit annoying to have such problems now with PMDG, I hope you understand me.Hopefully you find very soon the little bug which is eating in our computers all the good PMDg stuff...guenter steiner

The JS41 doesn't use the pmdgoptions.dll; although earlier aircraft do. Try reinstalling the other aircraft. Hope that fixes it.
