I installed Plan-g on Windows 7.  I had FSX running in the background when I was trying to set up the data base for FS9.  After a while my ENTIRE COMPUTER CRASHED!
I got the BLACK BOX.  When I rebooted I found that my entire FSX files had DISAPPEARD!  Totally Gone.  In Windows 7 PROGRAMS and FEATURES there was no listing
for Microsoft Flight Simulator FSX.
The only FSX folders remaining on my computer were the one where the flight plans are stored, and the other folder where the FSX.cfg file is located.
Questions:
1.  What could have caused this?
2.  I tried Win 7 reset to an earlier date.  No help.
     Is there any possibility of recovering FSX?  If so how?
3.  Has anyone had the Black Box experience with Plan-G?

Thanks.

Gentlemen:
I am about to install Plan-G for the first time.  Before doing so I thought I would read through the installation posts in the forum so as to avoid
any problems.

I have Windows 7, and the Gold edition of FSX installed which I understand includes Service Pack 1 + 2.  I also have the paid version of FSUIPC installed.
Is there anything else that I should have installed BEFORE I attempt to install Plan-G?  I also have FS9 installed.

Thank you.
Stanner
