Demonbuddy Crashes After Entering The Passcode

Hello,

I bought a lifetime BD key this afternoon and I installed by an installer, but after I entered the key and clicked login, the window suddenly disappeared. Here is my log:

2015-02-01 03:22:42,865 [1] INFO MainWindow (null) - Demonbuddy v1.1.2229.398 started

2015-02-01 03:22:44,386 [5] INFO MainWindow (null) - Logging in...

2015-02-01 03:22:44,827 [5] INFO MainWindow (null) - T: 5247269596071636560 H: 2156688958

Is there any way to fix it? I am using win8.1.

Thank you.
