Your amxmodx stopped work because now You don't have the call to metamod in his latest target line You have:
+localinfo mgamedll epodbot/epb.dll +localinfo mbotmod epodbot
no metamod call -> no AMX MOD X and no other fun plugins work...
Because it's impossible to get to correct work the line like:
+localinfo mgamedll addons/metamod/dlls/metamod.dll +localinfo mgamedll epodbot/epb.dll +localinfo mbotmod epodbot
(two times called mgamedll) - so it wouldn't work until THE_STORM will change epodbot into a metamod plugin (one reason more to do it). mEAn may call only one mgamedll - metamod.dll or not_mm_bot.dll. One of them will work - the other will not.
[EDIT]
But try this way:
+localinfo mgamedll addons/metamod/dlls/metamod.dll +localinfo mm_gamedll epodbot/epb.dll +localinfo mbotmod epodbot
Now it's metamod calling epodbot and dunno if it would work with mEAn.
This line seems to be too long - create in notepad the file called autoexec.cfg (if You don't have it already) in cstrike directory (You have there Your liblist.gam file) and write in it these lines:
+localinfo mgamedll addons/metamod/dlls/metamod.dll
+localinfo mm_gamedll "epodbot/epb.dll"
+localinfo mbotmod epodbot
Then remove that target line in the shortcut and try to start the game again.
