The F&%¤ed CSS

I was working on a CSS file, opened it up in Wordpad to change a line, reloaded it in Dreamweaver, tested the site a few times while saving the file and left the computer alone for a while to complete a large file transfer between drives. Came back and opened up my site and it was displayed without styling, so I opened up the CSS file to see if I made missed a } or something. Imagine my horror when the whole file is blank, just blank, and it's still 5,8KB! I suppose that means the file is corrupt.

I've googled all over the place without finding a solution to the problem, and I've never had this problem before either. I've switched between Wordpad and Dreamweaver a lot, but I guess things are different with either the new Wordpad or the CS3 version of Dreamweaver. Part of the file was based on my old CSS, but most of it was new stuff I had been finetuning for at least half a day this week making the new design as perfect as possible. Was going to post a quick snapshot of the new design so far, but now I'll have to rework the entire CSS file instead. This too, sucks.
