Okay, so I didn't get a chance to try a flight without FSUIPC. However, as somebody in a Facebook group suggested, I inserted the disc and chose to repair. After it was finished, I tried running FSX. I am no longer having the issue with FSUIPC, but a fatal error occurs. When I get the crash report, it says this:

 

Faulting application name: fsx.exe, version: 10.0.61637.0, time stamp: 0x46fadb14

Any ideas on how to fix this? Thanks,

According to the AVSIM CTD Guide:

 

Simprop.dll –

• Most likely a problem with the installation of Acceleration.  Try uninstalling Acceleration (go to Add/Remove Programs; look for FSX and click on uninstall.  It will only uninstall Acceleration.  FSX will still be there).  Run FSX once and see if this fixed the program.  If so, reinstall Acceleration with Admin privileges.  Run FSX again to make sure the problem is fixed. 

If problem not fixed -

• Remove your FSX or P3D.cfg and let the configuration rebuild. 
• If this does not fix the problem, rename your logbook.bin in the My Documents/Flight Simulator X Files folder and try running FSX again.  If that works, then you might want to download from the AVSIM Library a program called FSX Logbook Recovery 1.1 and try to repair the one you renamed.

Best regards,

I fixed the problem by repairing Acceleration, which I didn't do after repairing FSX. Now I'm back to the same issue on FSX startup with FSUIPC. This time, though, when I select to run it, FSX gets a fatal error and crashes instead of just closing. Here's on of the error reports:

Back to a crash in FSUIPC4.dll. I was going to try uninstalling Acceleration, repairing FSX, and reinstalling Acceleration. Any suggestions? I'm also waiting to get an answer from Pete at the FSUIPC forums.

Okay, as far as I can tell, I fixed my problem.

 

I think deleting a line from the registry was the fix, but I'm not entirely sure.

 

After I reinstalled Acceleration, which was my final step, the FSUIPC error reappeared on startup, but when I hit "yes" FSX still opened.

 

It looks like I might have to reinstall my addon aircraft, again I'm not entirely sure.

 

I also had to change my settings. Is there any way to know what they were before my issues began?

 

The final step will be a flight. I'll post back here if anything happens then.
