Hi Pete!
Just wanted to alert you to a problem that I had with the new version of FSUIPC (my prior version was 4.53). I installed to FSX SP1 and FSX crashed during initial loading giving simconnect.dll as the culprit. Initially thinking it was simconnect, I reinstalled it from the SDK 1A and got the same error. Figuring I now had a corrupted FSX, I went and did a Norton Ghost PC restore to get back to the prior state. I then reinstalled only version 4.70 (nothing else) and got the same error. Reverting to version 4.53 took care of the problem.
I'm pretty sure I can repeat this, and will get a log file to you when I can. If there is any additional information that I need, please let me know.
Cheers,
Mike T.
