If those maps aren't for esf 1.2 then u can't play them because it requires some files that are only present in the version that the map was made for. For example, esf_namek (an old map for esf 1.1) can't be run on esf 1.2 because it misses a file called e.g. namektree.wad or something like that. Try downloading the map you're trying to play at ESF-World, if you do that the missing files will come with the map and you'll be able to play it.
P.S. Try not to double-post in the future.
