7.3.5 RC registration problem

Try other way to unlock TLB:
Create file tlb.ini with text

Code:

[LICENSE]
PortableKey = <NAME>, <KEY>

Replace <NAME> and <KEY> with your name and key.
Place tlb.ini into True Launch Bar installation folder. By default this is C:\Program Files\TrueLaunchBar

Now you can enter empty license key or restart True Launch Bar.
