Hi guys!
I wanted to ask your help.
I formatted my computer and put windows 8.
The counter strik is not working, it is not installing.
When I click on the installer Incone counter strik, the following appears:
No steam was not successfully installed the following reason: cstrike/de_storm.wad: This file contains invalid data. Close the installation wizard to try to install again counter strike 1.6 - No steam

Thank you

try deleting your steam and all its folders and re dowloading it
