@DABhand:
I think it is possible to run CSS on LAN without a Steamconnection!
@muJi.fiGHt3r:
How did you manage it ?!
On the DVD are CAB-Files. You can open them by e.g. WinRAR. Then You extract ALL GCF-Files, that are placed in the CAB-Files, on your harddisk. After that you open the GCF-Files (one by one) and extract the gamefiles on your Harddisk (all in the same "root"-Folder). Then you take the Traget21 Fix-cracked-Files and take it over the existing original one.
Did you make your copy of HL2 run without steam activation
YES
Is it a non-english version ?!
YES, german version. But the FIX-Files originally written for the english version.
Please tell me how to do it !!!
I think i've done it^^
AH ! Beautyful !!! 
But i want to run CSS in a alone-stand-version
PLEASE HELP ME
