Thanks for all the help MCR and Accumulator
I started it up, and it seems to run fine. It is a bit slower than 3.2, but then again, I have a slow computer. I just need to adjust some of the graphics profiles, and re-tool a couple of the keyboard controls. (The battle map movement is difficult because of the slowness, but I will change that soon.)
But I fooled around with the Geoscape, and did a quick battle, and so far I think it is looking like a great improvement!
I will post if I have any problems.
