I used HLDSUPDATETOOL to install a fresh CSS server.
I extract Metamod, Sourcemod and CSSDM into a folder and put my server.cfg in it as well, then paste the ADDONS & CFG folders in cstrike.
Here is a .rar of the MM,SM and CSSDM that I put onto my server.

I use these launch options as stated before:
"C:\Valvex86\CSS DM\css\srcds.exe" -game cstrike -tickrate 100 -console -insecure +maxplayers 64 +map de_dust2 +hostport "27017" -debug -nobreakpad"
and that's it.
