ultimate spider-man recover

Hi guys.A few week ago,i installed the game Ulitmate Spider-man for my pc.Howevr,one day,my little brother accidentally uninstall it.So,i try to find all the game's cd but all i can find is the second cd and the third cd(the game has 3 cd).So,plz,if anyone know how to recover the game without the first cd,plz help me.
P.s:i heard about a recover software,but i didn't try yet.Sorry for my english

I've got the game also but than I've got in DVD format.If I were you i would download the game from somewhere
in DVD format and you'll have the game back and you can play it again
because it is in 1 DVD instead of 3 Cd's.
