Thank you for your info, Markoz.
I am running Vista 64-bit-sp2. I have a2 Quad pc w @2.33GHz Ram-8.00 GB. Drive-c- 1.82 TB. Video card- GEForce GT 440. Video card Mem-1.00 GB. Running as Administrator. Running FSX in C:\Prog Files [x86].
I have uninstalled and reinstalled 3 times. Same results.
I hope an administrator can also give advice on what to do.
Once you read this, would be appreciative to receive any other
advice.
