icloud not working on ipad 2

i just purchased an ipad2-synced it with itunes on my pc and started icloud. I also have an iphone that I synced and started icloud on. Now, icloud does not seem to be working on my ipad. Automatic updates were sent to my PC and iphone, but did not sync with my ipad. I am trying to access documents that are in the Pages app- they are on my PC, on my iphone, and in the icloud, but I can't get them to go to my ipad. When I try to go to the icloud on my ipad, it acts like icloud is not set up on my device, but it already is. All settings are turned on, and it is listed under settings. I can't get to the log in page to access the cloud via the ipad. Any ideas?

Thanks!
