What are those steam cracks and how do they work with rev?You can't find nosteam release without revemu, there is few steam cracks but those are used individualy. VUP, that's for servers anyway!?
It's actually good that Valve is releasing new updates as it makes possible to include updates to client patches too - such as rev emu. I played CS:S for years with the same outdated version because there was nothing wrong with it. Updating rEV would have given me no useful benefits. Now with Orangebox updates old versions are incompatible and thus players are forced to update.
I thought that Vityan had some client patch too but apparently not.
Hmm... what does AllowUnknown=False then do if everyone has rEV anyway? It might not have any effect at all or then we are just banning potential players for no reason.
