DMCA not RIAA sorry but yeah steam is likely to blame for its use.
Believe me i tried to save an offline profile but the message was you need to go online for that :S i kid you not. The problem as far as i could guess was that steam wanted to make sure the copy was mine and since it had newer been activated online i was stuck.
Newer versions of steam might have fixed that but at the time atleast there was nothing i could do besides use steamemu and i had to borrow one of my friends internet to get it then drive 120 km back with a cd
with the 2 files needed on it needless to say i was pissed . Took me about two months to get internet in my new flat since they had to dig in new cables, the old ones had rotted away so where useless.
So some might say why didnt i bring my pc then to create the offline file heh would have been a bit of a hazzle since i have no car i drive a motorbike and my pc is a hightower model so besides looking funny as hell it might not have been the best stunt i could pull off

I could more or less read the newsline "man killed by his own PC hehe".
Productivity is a state of mind.
