Hi Pete,
since I tried reinstalling FSUIPC and deleated all the logs I can right now not give you a log of the crash, but I will as soon as the Crash happens again tomorrow (and I am quite sure it will if I try a few flights).
Here is the rest of the data you requested:
API dll version: 10.0.61472.0 (fsx-sp2.20071210.2023)
Date of last change of the api.dll: 10.12.2007 21:30
I am using a German version of FSX. The crash happens with both, Acceleration Pack installed or Acceleration Pack not installed.
I will try changing that line and let you know tomorrow.
Another thing you should know:
Since I had to wait so long until you were back from the Holidays I have meanwhile tried a complete reinstallation of my whole operating system (Windows 7 Professional x64).
After the reinstallation the crashes were gone until I reinstalled the Hotfix for ASN.
Even completly uninstalling and deleating all remains of ASN does not solve the problem though.
Since the problem happens even after the reinstallation of Windows I am sure that it can be bought back to ASN's Hotfix.
My other Addons currently installed (I didn't install many of them after I reinstalled Windows) are:
FTX Global, FTX Global Vector, PMDG777, A2A C172, Realair BE60 Duke, FlyTampa Dubai, Mega Airport Düsseldorf, FSUIPC (Payware), ASN (Problems appear since the installation of Hotfix 1, before I isntalled the Hotfix the RTM version worked fine!), REX Texture Direct, FSInn, RealityXP GNS530, GNS430 & GNS WAAS Unlimited Pack.
