Both. WIP 10 throws the same error, 1.0 has a metamod and a normal one, the metamod throws that error and the normal one crashes without an error (?)

I have the original CS retail (1.0.0.0 retail, i dunno what that is equivalant to mod-wise). Since I have this problem with multiple bots, is it possible that the bots are based off of a framework that is newer than my CS? If so, is there a place I can upgrade my CS retail to whatever I need? I have looked for upgrades but all I have found are 121-meg "full install" downloads and a 1.4 to 1.5 patch for the mod version.

Thanks in advance.
