Hello Pete,
1-FSX Gold is simply FSX Deluxe (on 2 DVD's) and a third DVD containing FSX-Acceleration. So in summary: FSX+SP1/SP2/Acceleration in one neat little install.
2-Interestingly after re-installating FSX, World of AI packages, and a single SU-70 from http://www.fly-euroharmony.com/site/mainfleetpage.html (the SU-80) all is back to normal EXCEPT for the pilot logbook which now displays totals with no details visible. Granted I only flew a quick tutorial and did the solo checkride as a test.....I will see if the full logbook entry shows up in free-flight mode. If it does not I will delete the logbook.bin file which is in "My Documents---->FSX" or something like that and see if it sorts itself out (presuming the .bin file is replaced again by FSX).
I don't think the add-on aircraft would be the issue. After all..they were working fine (as was FSX) before this happened and a search of the EH forums showed no similar complaints. I also do not have the SU-80 loading by default.
Again....I run no other add-ons. I was hoping to use Flight Logger and eventually Pro Pilot (http://www.fly-euroharmony.com/site/sugdownload.php) which require the use of FSUIPC...beyond that my only future add-ons were IVAO/VATSIM.
There are no other MS FS's loaded on this machine. Only IL-2:1946 (vanilla), Bioshock, The Witcher, and Fallout 3 reside on this machine (outside of KAV and Adobe Elements for screenshot editing).
3-I understand and can accept what you are saying regarding possible corruption. The issue I have is that all worked as NORMAL prior to installing FSUIPC4 4.40. Unless FSX-Gold has re-introduced a 2 year-old bug (hardly shocking if true) I can see no other reason for such corruption to occur UNLESS caused by some interaction between the FSUIPC install and FSX.
I am not overly willing to attempt to recreate the issue as it took a second use of the license to sort out (I did not know to try the .bin delete....and no guarantee that would fix the issue) and a couple hours of uninstall/defrag/reinstall/defrag blah blah blah :).
If there might be a log thrown somewhere you would like me to look for I am happy to do so to help resolve this. Ditto any further detail I can provide.
I appreciate your responses despite my not even being a paying customer at this time!
Regards
Ted
