OK, so I downloaded the Windows 7 iso file, went through the hassle of burning disk, etc, and it didn't work; so I ended up upgrading to windows 8.1 64 bit this morning, got everything reinstalled and up and running; it recognized my memory fine, and now I have a least 6 GB of unused RAM. However, once again to my horror, I was just writing a script, and it gave me the dreaded "Unhandled Exception has occurred.... System.OutofMemory"... From that point forward, interaction checking doesn't work, and then if I try to view an imported item, it gives me the "There is a Problem with Adobe Reader" error, and I can no longer view imported items, print items, and eventually it will freeze. Basically $300 down the toilet and a whole day wasted. There is clearly some sort of CUMULATIVE problem with AC (outlined by others here on the userboard) that invokes a freezing up of the critical processes involved with the program, presumably on the basis of some sort of real or perceived memory consumption.....
It leads me to believe that the only solution for me is to constantly open and close AC and reboot computer on a twice a day basis forever, or switch to AC in the cloud, or change to a better EMR
