Hello, new to the forums so apologies if this has been answered many times before but I can't get Railmaster to activate no matter what I change, disable or try! This is driving me insane! I have emailed support but not had a reply so I thought I'd see if anyone here has any suggestions. I've read the firewall and antivirus document and have tried with both configured as suggested and even diasabled alltogether. I'm running the latest s/w on Windows 7 Pro SP1. Program is set to run as admin and folder has correct write permissions etc. Each time I try I get an error saying the key was not downloaded correctly. This has to be the hardest software I have ever tried to install! Thanks for any help you can offer.
