cannot download email attachments windows 7 lion bootcamp MacBook Pro.

I cannot download or upload email attachments with windows 7 on lion bootcamp. Attached files such as xxx.doc, yyyy.jpg, or zzz.txt erroneously try to download as *icloud* and of course fail. By * I mean alphanumeric string. icloud mail tries to download perfectly good files as gibberish. On my mac lion side the mail function works fine. On the bootcamp side all non-icloud mail functions and browser functions work fine. I can easily send, forward, reply to and receive icloud mail. The only thing wrong is that I cannot sucessfully unload or download icloud email attachments.
