Thanks Norm,

The problem is the same as mentioned in post #112 of this thread and if I recall correctly in another thread. When you added support for PBP3 older versions without the registration code from MeLabs does not work. The screen shot in post #112 is typical.

Sooner or later everyone will be updated... but in my case I have more than three machines with PBP and I really do not want to pay the fee multiple times. So I am still using PBP2.6x on a few.
