Hi I have had a look on the forum and saw another user having this issue it was resolved by adding an exception on the firewall for activate.exchangeit24.com but I was not able to add to that topic so created my own.
I am having the disabled license 28082 issue so i added the exception but this has not resolved the issue I have also updated to CE 6.5
This message is because your license was moved to a different MachineID on the 20th May, it was however moved back again to the same MachineID on the same day but it now has a new serial number that needs to be used.
You will need to delete the existing license file on the license server and then add the new license.
I will email you details of the replacement license to your registered email address shorty.
