Somebody please help me.........

-I ve managed to create a working image with Games X copy and i installed HL2 from this image...everything ok till now!!!
-i have a valid steam account.
-i unlocked CS:source and HL2 from internet (with the help of some files already downloaded from a friend of mine).If u right-click on them (in "play games" on steam menu) and select "properties" u can see "Status:Ready to play" "Amount acquired:100%" and "Offline mode:Ready".But i was not able to play using this image cause of "Emulation software detected....etc" (securom obviously).
-i downloaded Emporio's fix, Hijack's dll 1.5 for XP SP2 users and Hijack's No cd crack (i dont know which version) and i apply them correctly i think!!
-i managed to play CS:Source correctly!
-BUT when i try to play HL2, during the game, when "LOADING" message appears, i wait for some secs and then a message appears, i turn back to windows and the game has stopped!!!!
The message is: "Source - Fatal Error : Could not acquire necessary game files because the connection to Steam servers was lost."

What have i done wrong?
Somebody please help me!!!!
I dont know what else to do!!!!
