Hello I have been having some errors on my flight sim ever since about the time I installed Real Xp GPS 530 and the RealAir Marachetti SF.260.Oh yeah I also installed FSBUILD around that time..I have an AMD Athlon 64bit 3200+ with a gig of ram and a NVIDIA 256mb geforce 5500fx with a soundblaster live 5.1I don't understand it but in the middle of my flight I get an error stating something about windows having to adjust my virtual memory and PF usage.. I don't know exactly what the hog is or where it could be.. I have the Marachetti vc on medium did have it on high till I got that error..The programs that are open when I am flying are squawkbox and flightsim, activesky, and fsbuild..I am at a loss and it is now ruining my whole flight experiences.. Really hurting over here..Anyone have any suggestions or clues for me?One of my error signatures was as followed.. szAppName: fs9.exe szAppVer: 9.1.0.40901 szModName: hungapp sz ModVer: 0.0.0.0 offset: 00000000Technical info as followed: C:DOCUME~1JWLOCALS~1TEMPWER44.tmp.dir00fs9.exe.mdmpC:DOCUME~1JWLOCALS~1TempWER44.tmpdir00appcompat.txtShould I try to re-install my flight sim..
