I have a (previously) working HEM2 license. The new update today (.6384) resulted in it loading once and asking me for my license. I entered my license and it worked okay. The second time I opened it it asked me for my license again and this time it's telling me there are "Errors while registering with server. Retry, or if problems persist please contact customer service". So, I retryed, and now I am contacting customer service.
Running windows 7, already went through the FAQ for license fuck-ups; deleted the license file and tried again, no change, am running as administrator etc. etc.
