Thanks for your quest, rik

The simulator gives the error and will not run.

The same error message occurrs when I run dxdiag.exe.

The Real Flight Tech support said it was not a problem with their application, but rather, was a problem with the win2k system files. The fact that it occurrs when dxdiag.exe is run, supports their diagnosis.

I forgot to mention above that I have completed a successful scannow, which seemed to replace "most or all" dlls that might have been damaged or missing due to the major system failue (my first in 9 years) that occurred about 3 to 4 weeks ago.

Am ready to try any suggestions, and report back the results here.

My best, Peter
