Well, I broke down and installed it myself. It seems to work beautifully!! I looked all over that website, and I didn't see anything about maybe it doesn't work on Vista, or something like that. But I didn't see anything like that.
Let's start from the beginning. Are you using a laptop or desktop computer? For a laptop, you should have downloaded the 64-bit version. Or for a desktop, you should have downloaded the 32-bit version.
So double-check you got the right one.
For me, on Windows 7, when I first double-clicked on the EXE file, I got some kind of error message (I don't remember the exact words). I think you should get that error message too, on Vista, but I'm not positive.
Ok, I'll stop there for now. Let me know if you've gotten this far, and I'll go on to the next steps
