I went to compress the files on my hard drive because I was running out of space. I was going to use the standard Windows compression. Then this message pops up telling me that some files Windows needs to operate have been replaced with unrecognized versions and windows needs to replace them. It wants my Windows 2000 disk. I don't HAVE one. Well, I do, it's in the other office, but I don't want to go get it. Dammit. I'm going to try to uncompress the files and then just restart. Hope that works.
UPDATE: I just hit "cancel" and it let me use the replaced files. So I'm good, it's fitzed.
