Memory issue?????

[Guest coolfront55]

Hello fellow simmers, I can't remember the post, but awhile back, someone had a problem with FS9 disappearing and going back to desktop. The responces lead me to believe that it was a memory problem with FS9. Heres my issue. I just purchased Aerosofts EDDF scenery, and when flying PMDG 747 from EDDF to KBOS, about 2 hours into the flight FS9 shows a box saying not enough memory, and DISAPPEARS (has happened twice)! I know I have enough space on hard drive (160GB).I increased virtual memory in my system setting and it happened again. I did do a flight from KSFO to PHNL with "Queen of the Skys" and had no problems, and thats with FlyTampa scenery for KSFO and PHNL scenery from Lago. I am now testing the same flight (EDDF to KBOS), but this time with PSS T7 to see if 747 might be causing it. When I fly I have "Voice box, ActiveSky 6.5 and SQ box 3" all running at the same time.Any help would greatly be appreciated.Thank-you and God speed,George

I read threads that gave me some insight into the problem. Has anyone found a work around solution for this memory problem?George
