As the colleague KWo said you must make liblist.gam to point your metamod, and metamod plugins.ini must point EPB and AMXX.
Add this line to your plugins.ini file
win32 EPODbot\EPB.dll
and edit the line in liblist.gam to point metamod, the needed line must looks like that
gamedll "addons/metamod/dlls/metamod.dll"
Thats all.
