License Registration nightmare

Reinstalled latest SC on new Win10 machine. I cannot register the license. I made the request for new License ID on NetMake website. When I try to register I get error message saying the username or password is wrong (although I use the same credentials I use to login to my account on SC website). Neither On-Line or Off-Line is working. When tried off-line I got (some NON-ENGLISH message in red) which of course drives me nuts.

Any ideas why his might not working ?

Thanks - ARTHUR
