Common Elicense Problem and solution
I bought the TEW10 game, the demo worked fine, but as soon as I installed the e-license the game wouldn't launch and I couldn't figure it out for the longest time. Then I looked up my anti virus program and why the e-license wouldn't work with it on google. Anyway, I use Zone Alarm and when my wife installed the program she also installed the tool bar that came with it. I discovered that the tool bar was blocking the e-license. I don't need the tool bar so I uninstalled it and now my game works fine. So maybe your anti-virus program has a tool bar that's blocking the e-license, look in your control panel, uninstall programs and look for your anti-virus program name and see if there's a tool bar there too. If so, uninstall the tool bar and see if that helps.
I hope this helps others out there, also if I posted this in the wrong place, I apologize. It just seemed like the right place to do it since anyone having the same problem with any Greydog game should be able to use the same solution.
