Hi folks. I hope someone here can help me. I've just installed BTB for the first time on Windows 7 64 bit. I've downloaded my license and put it in the root folder. When I double click the icon to start BTB I get the message "Do you want to allow the following program from an unknown publisher to make changes to this computer?" I click yes and nothing happens. To see if it was a license problem, I removed the license from the root folder and tried to start it up and I got the message "Lock System. This software won't run without a valid license file. Either a valid license could not be found or your licence file has expired." I've got a feeling I'm missing something pretty simple but I'd appreciate it if anyone can help me get BTB to start up. Cheers Richie.
