Can't open new Keynote documents in iCloud

Figured it out after reading a bunch of different articles on similar topics. The solution is to log out of your iCloud account in System preferences and then log back in. I have a hunch that this problem was created when I changed my iCloud password. While the solution is easy, it is also a big hassle. Now iMail is in the process of downloading over 4000 messages! Good grief.

No replies. Am I the only one with this problem? Tried again. Started a new document in Keynote on my Mac with just 5 slides, saved it to iCloud Drive. The document opens fine on my iPhone and iPad but when I try to open it on the Mac, I get the message that it cannot be opened. Indeed, I cannot open any of my Keynote documents that are stored in iCloud Drive. I am using the latest Keynote and Yosemite on my Retina MBP.

Try downloading the document you want to open from your web browser rather than trying to open in the application. Open up your iCloud drive with your browser, find your document. Click once on it and then click on the download icon. Then open it from your downloads folder.
