w_kevlar.mdl and other models missing in Your CS/CZERO isn't related to pb mm. Either You have something wrong with Your condition zero.gcf file, You are using some older (and not updated) version of CZERO or Your instalator was corrupted. Another thing is also this - You are trying to load any older plugin with my A-I-O which is not precaching the model w_kevlar.mdl - which says it's missing (even if gcf and everything is OK). None of A-I-O plugins needs w_kevlar.mdl model. Just disable at all amxmodx (in metamod's plugins.ini, not in that amxmodx' one) to see if the problem exists or not. Nobody at this forum had that problem with A-I-O, so I don't think A-I-O is the cause of the problem You are experiencing now.
