Unity / Unity iPhone crash on start (silently)

Okay - I had installed Unity+Unity iPhone for some time on my Max Mini (10.6.2) without licensing it, because i wanted to make up my mind about the personal license money spending (already did some unity iPhone dev for the company i work for - on a different Mac Mini). Now with the great 3.0 preorder offer i finally jumped into it.

But guess what:
After i typed in my freshly paid Pro serial in the license dialog it said licensing all okay and licensed, ready to go. But now when i launch unity or unity iphone it immediatly crashes silently, without any further dialog - except an entry in the crashlog DB. I even deinstalled/reinstalled and finally run the Pace/Interlok script from Pace’s webpage - but still no success. Unity completly refuses to run now. That’s frustrating for sure …
I’ll post a excerpt from the crash log if this helps…

Strange :

if i rename the folder “Library/Application Support/Pace Anti-Piracy” the register unity dialog appears again. But i don’t want to register a second time for sure because as i know we are only allowed to license two machines with it…

okay … booting into my 10.5.8 backup OS partition and bringen the ilf-license file over there and do a manual register works in 10.5.8. So it might be a problem with my 10.6.2 OS partition…
