Unable to log into WPMU from wordpress dashboard

I uploaded the wpmudev-udates folder to wordpress, but when I try to use the wpmu dashboard I am unable to log in. The area where I enter my id and password will not appear. It is like the dark blue area when I enter the information is stuck behind the light blue area that contains your icons. I wish I could send a screenshot, it is pretty difficult to explain. I tried using a different browser, deleted the browser history. I am stuck.
