I'm trying to install Evolutions mod, but whenever I try to open it with FLMM from the website, it keeps trying to open it as a compessed zip file, and finds it corrupt. Then, i try to save it on the hard disk, and open it from there, it says the central directory cannot be found (which I don't really understand). When I save the patch to the disk and open it, it says it's unzipped and installed, but then it says there was a problem inspecting the files in the /mods folder.

I'm running Windows XP so rundl32 opens zip files instead of WinZip, but then I got WinZip and it doesn't work either. When I try to open the files without the flmod extensions, it shows up empty. What's going on?
