A crack is the following
(1) To break into a computer system. The term was coined in the mid-80s by hackers who wanted to differentiate themselves from individuals whose sole purpose is to sneak through security systems. Whereas crackers sole aim is to break into secure systems, hackers are more interested in gaining knowledge about computer systems and possibly using this knowledge for playful pranks. Although hackers still argue that there's a big difference between what they do and what crackers do, the mass media has failed to understand the distinction, so the two terms -- hack and crack -- are often used interchangeably.
(2) To copy commercial software illegally by breaking (cracking) the various copy-protection and registration techniques being used.
Rookie is not steam, nor does he reprent them. To be frank if you contact sega there is a good chance they tell you to contact 'valve'(the company that owns steam). It depends where the fault lies. Now lots of games are filled with bugs, and game companies don't get sued over a bug.
e.g. when diablo 3 came out and everyone got the error not allowing them to play there game blizzard did not get sued.
My guess would be that it is a problem easily fixable, and may already have a fix. If I were you I would contact 4 or 5 admins of sports interactive and ask them to look into your problem. As well as surfing the bug page.
And to an observer I am sure rookie meant no harm by his comments or tone, its just this knowledge is pretty general knowledge for steam users, and I'm sure he doesn't have the time to know how computer / steam 'savy' everyone on this site is.
