Ah, now I understand.
Typically, what I do, is serve one general stylesheet to all browsers. Then, if necessary, I use a Conditional Comment to serve an alternate stylesheet (containing only overrides) to those IE versions that need it.
Are you uploading your file directly via FTP, or through a CMS or similar means? Many CMSs have severe issues when parsing comments.
