Activating OptiSurface Designer and Firewall Parameters

If you're having trouble activating an OptiSurface Designer license, it could be due to your antivirus or firewall software.

Try this:

Disable firewall and virus scanner for 1 minute while you activate the codes.
Or connect to internet via another wireless connection if on a laptop.

Port: Port 443 is used for communication but Port 80 may also be used as a fallback.
