'five minutes' or 'already a crack' would mean, CL was cracked or one of the crackauthors is sitting in the CL- office. Both would be very interesting (think of the promised security of your personal data) but I really can,t believe that (the second choice).

CL uses a third party tool for the P5 security stuff. Those security tools are usually part of several different applications from different developers. It is a good guess that this security tool is used and cracked already. For a cracker it is probably as simple as pointing his cracker utilities from application xyz.exe to poser5.exe and the crack is ready.
But I think it dosen't matter. In former messages CL stated that they will generate at least 3 different response codes per Poser 5 serial, so piracy is possible even without a crack.

I will buy the update anyway, because I preorderd from Softline before I did know of this activation code and it is to exhausting to cancel an order from them. ;P
