you have a syntax error somewhere in your config: ofp expects a character that just isn't there
fortunately ofp gives you a little hint in the errosr message. it normally reads something like
error in ...\...\config.bin\class cfgvehicles. encountered 'xyz' instead of 'abc'. restart ofp, read the error message and search that part of the config (in my example the cfgVehicles part). it's normally an error like a komma instead of a semicolon, etc. so check your config carefully. if the error message reads
... encounered 'c' instead of ';' you most certainly missed a semicolon, c might be every letter here.
edit: after reading your post a second time i would say you missed a '=' somewhere as it clearly reads in the error message. now read the part of the config where the error is supposed to be and check every line where the should be a '=' somewhere, namely all arrays like wound-definitions, hiddenselections, weapons/magazine definitions, etc.
