When I try to activate the license, I keep getting this error ?

I have already set the IE settings to the bottom to allow everything and turned off the firewall/antivirus protection once.
Can I change the browser? When I click on "open in a new window", the message that the link has expired appears immediately in the new window...
Also used the Access Manager and I am registered but I am unable to add a license or see anything.
I am the Administrator so I should see everything.
