it worked for beta and some time until now. I made some search and found what went wrong
acording to valve web page about vpk cs go has a new type of vpk system= vpk2
the difference is:
Footer
VPK2 adds a footer section that contains extra CRC data for pure mode "so the dedicated servers do not need to compute them at startup but can be checked with the command sv_pure_checkvpk".
so if you want hacks to work now single crc bruting wont work. we need to brute 1 more thing but what?
