Cannot read documents on iPad's iDisk app

Hello,

I would like to be able to access documents that are on my iDisk from my iPad via Apple's native iDisk app. However, any document I place on the iDisk and attempt to open on the pad will not open. I will get a message saying that the document cannot be viewed because the document version may be unsupported or an error occurred while reading it. I do have Pages on the pad. I've tried saving as Word documents, (both .doc and .docx), Pages, and even plaintext, and it seem no type of document can be recognized or opened on the iPad without error.

By the way, this is the same for my iPhone's iDisk app as well, so it's not just the iPad.

Has anyone seen this or know why this might be? Thanks for the help!
