AdminCP login: That action could not be completed. Please try again...
 

I am currently running vB 5 Beta 10 on my local system using xampp. Everythings works fine (as fine as the beta version of vB 5 can work at the moment :)), but whenever I try to login to the AdminCP, all I get is this error:

"That action could not be completed. Please try again, and if this occurs again please contact the system administrator and tell them how you got this message."

Here is an image, that displays what happens when I click on the AdminCP button (or Admin in the footer):

When I enter the link to the AdminCP directly (localhost/vb5/admincp), I get a blank page.

What am I doing wrong?
