Yea, did some research and also asked a friend who works in SI
about this and he said the error is actually 'intentionally' put in
by SI specially for pirated softwares.. I don't know how it
actually works but yup, whoever that has the 'ehem' version, be
prepared to see the error when you reach at least the 2nd season or
at some point in time during your gameplay.
Damn seems that I have to go buy the original then...
