WordPress MU

Hi,

I just want to login to my wordpress, but it doesnt work.
I enter my username/password, i press enter (or click login) and get back at the login page again.

When I enter wrong details I get a warning (username/password incorrect) but when I enter them correctly it does.. nothing.

I think something with cookies, because its working on another computer.
However, this computer just allows cookies and my wordpress is at trusted domains.

Maybe its a internet explorer thingie, i dont know.

Is this for a wordpress multiuser install some where? How about some links? are you the admin for thias install? Is this account created at that blog or wpmu install? Some details would be helpful.
