@Sailor Steve: yeah, i WISH i could just use the 4 gig patch. that'd be nice. unfortunately tho, while my computer itself is indeed a 64-bit machine, my copy of Win 7 Pro is only 32 bit. And no, I cannot upgrade this version without paying for a full Win 7 Pro 64-bit version. You see, this is a network install of Win 7that came on the computer (bought off Craigslist, but totally legit) and Micro$oft does not allow network installs to be upgraded like they do with the disc version.
VERDAMMT!!!
I see someone else here IS successfully using GWX + MFM. um How please?
What are the minimum system specs to run GWX + MFM (+MEP too) anyhow? I'd'a' thunk my system was up to spec: Pentium D Dual 3.4Ghz, 3Gig RAM, GTX560 Ti 1gig graphics .. i mean, criminy! what sort of system DOES work for this?

I certainly find it intersting that MFM runs just fine on my machine with Vanilla 1.4b, but not with GWX ... once i get my GWX soup done and patrol a bit, I'll try NYGM too, see if MFM works there.
