Thanks for the help, Joe!
I deactivated my antivirus but it didn't work. Installation was okay, but the program would still freeze. It was working fine with the first release, but started freezing with the updated version.
I'm also fairly certain I have the latest .NET framework as I believe I had to install it for a game or something? I'll check it out on my Win 7 machine later. <_<
On Win 8.1 I tried running the program on compatibility mode with Windows Vista SP2 and it seems to be working now. lol
