Sim1.dll is causing the CTD.Check this thread on VATSIM for assistance on sim1.dll CDTDs.Cheers,- jahman.

thanks for the help, what can I do about it?

Did you check that thread?Cheers,- jahman.

yes but I can`t really understand it and there is lots there

I have disabled UAC, would that help?

Since your CTD is occurring during a VATSM session, you might have better luck if re-post your request for assistance there.

I have disabled UAC, would that help?

Generally you should always run FSX with UAC disabled.Also any software installed while UAC is enabled might not install correctly, so you might cwant to consider uninstalling and reinstalling any add-ons installed while UAC was enabled (especially VATSIM software, i.e. Team Speak) so you can be sure the add-on is properly installed.Finally, enable Windows Update and apply all updates to make sure all your MSVC and .NET Runtimes are fully up tp date.Cheers,- jahman.

Im starting to think its either FSUIPC or FSCopilot (FSINN) which are the 2 required programs for connecting to vatsim. I have vaguely heard something about FSUIPC which you need to make FSCopilot run, anyone know anything on that topic?

Are you running any aircraft from Project Airbus? If so, remove them from the SimObjects folder. See here.VATSIM FSInn installation, troubleshooting and FAQ.Good luck!Cheers,- jahman.

No, thanks for replying again ;)
