"Memory" error freezing fs9 on final approach to SF's KATL.

I just recently started having problems with FS9 freezing up and then generating the "Your computer has run out of available memory..." error when on final approach to Simflyer's KATL. My computer is not overheated, it has plenty of memory (both hardrive and ram) and I've also increased my Page File setting on my DELL XPS from default 1536MB to 2536MB based on Eric's past success. However, fs9 still freezes up on final at SF's KATL. Could part of the problem be because I just recently installed fsgenesis American Data - could there be a bgl problem? Any help would be greatly appreciated.FYI: P4 3.0GHZ, 2 GHZ RAM, Radeon 9800Pro, FS9, PMDG and XP homeThanks in Advance,Alex
