how to use EVE and CRC files?

hi ben stomping over this http://www.dmm.co.jp/en/dc/doujin/-/detail/=/cid=d_083516zero/
on dmm
i also found this site http://myuu-freeeroga.com/game/DLpage.html

site says game has battle fuck and it's free so i dl it ending up with EVE-file
my first thought wtf is a EVE-file

so i searched around found this http://www.src-srpg.jpn.org/
read there using google translation says its convert EVE to CRC makes game playable or something

found this on the site http://www.src-srpg.jpn.org/play_installmanual.shtml
take me there http://www.src-srpg.jpn.org/play_newinstall.shtml

now i managed to start the game but after the intro i get this error http://img4web.com/view/RNEXFM(

so can anyone tell me how to get it to work?

or if there better ways to use these eve files?
