PAHUDreg code = PT3 code?

[melioris]

since PAHUD still isn't working for me (and I am trying to remember what year I made the PAHUD purchase to search in my email archives for the my reg code) I tried my PT3 code. It doesn't work, PAHUD still gives me the same error at startup. But shouldn't the PT3 reg. code work as PT2 and PAHUD was an extra bonus for buying PT3?
