Hmmm, that sounds rather as if Ie isn't looking for the latest version of the page but is using stored ones on your computer. Try clearing your temporary internet files, and also check your settings to make certain ie looks for the latest versions of pages, ---- that used to be in advanced in Ie 6 and 7 but i'm not sure where it is on 8.
Also, check your security, sinse ie's security settings can cause issues of this sort especially when downloading or streaming files is needed.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
