Tizer

I'm trying to activate a newly purchased license key and i get the error below. I'm running the as of the time of writing, latest version. I can connect to update the program no issues. But this error still persists. I can't find "customer support team" anywhere on Ccleaner website to get assistance as is mentioned in the pic. I've knocked all anti-virus and firewall off, note that the updater server easily connects with or without these on/off.
