Is this just Vista, or what?

I've been forced into downloading and extracting mods one file at a time. I have Vista Home Premium and JSGME has been installed - and I used administrator rights to get it to generate the appropriate "MODS" and "BACKUP" folders. HOWEVER, when I attempt to extract mods I've downloaded into either the "MODS" folder, or another folder I've created, it gives me an error along the lines of "Can't extract to C:\SH4...\MODS..." I end up having to extract to Desktop instead, and then manually overwrite the existing files in SH4 (not a great idea, to be sure!)
What am I doing wrong?
