activate thru proxy?

I began to use em client in local network, with openfire server. now my demo period is over and I applied for a free license, but I cannot activate my em Client because it does not have proxy support, is there any other way?

ok, I’ve done it by copying emclient folder from “application data” to another computer with direct access, registering and then moving back the whole folder, now I have an activated em client behind corporate firewall

please provide me tcp port for this service

eM Client uses standard ports 80 and 443.
