Go to my signature and get All-In-One package from the link.
Rename Your current addons folder to something like addons_old (to have a copy of this what Your are using now). Unzip the all-in-one in tha main cstrike/czero folder (depanding which mod You are playing). Start the game and check if it works (as it is - without changing anything in any cfg). The only thing You may need to change is just enable CSDM from the menu (OK - use Your old users.ini to have Your users/passwords). If it works - You are installing something incorrectly while installing manually. If no - something has to be worng with Your steam (that tip with All-In-One was always helpful while the people were asking me here and at bots-united board).
