The problem was solved with beta update (5006)
Code:
./steam -command update -game cstrike -beta hlbeta -dir .
and with installing
KWo's CSDM 2.1.2 hlbeta
But the problem still is: CSDM 2.1.2 is not working with 4883 build on FreeBSD 8.0
Tested with clean steam 4883 hlds build with AMXX 1.8.1.3746 without any thirdparty plugins and with CSDM 2.1.1 , 2.1.2 , 2.1.2 hlbeta , 2.1.2k by KWo and 2.1.2k-hlbeta too. Btw, it was tested on two different machines with the same freebsd OS. And there was same result...
