Would it be possible to paste the entire error message here? Make sure you installed the license as an Administrator (Right click -> Run as Administrator) when launching and setting the license file.
It appears the applications or user settings files is corrupt. Is this a new install? I would attempt a full uninstall-install is possible.
I look forward to hearing from you.
Apologies for the delayed response.
The issue was solved without any intervention.
Thanks for your support.
