Thanks for all the advice guys. Right now, I'm going to stick with the RAM upgrade. This is the only machine I have and I use it for everything. FS9 is important to me, but not the most important use. I have Silver Wings and REP, plus a custom water environment, thanks to Shane. I downloaded VOZ, but am trying to figure out which backup to use to remove Silver Wings before I try VOZ. I guess I just added too many things in too short a time without proper notes explaining what was done and when/in what order. So I'm a little confused at this point and I have no one to blame but me. I'm even considering re-installing FS9 and starting over from scratch. I just dread the work/time involved in doing that. At least I have all the scenery/enhancements and most of the aircraft so I don't have to do a lot searching and downloading if I re-install. Again, thanks. I'm just going to give it all some thought and go slow. And if I do re-install, this time I will make in depth notes of everything I do, not to mention backups.
