Resource not found error solved!
Heads up everybody, it seems that I finally managed to kill the "Resource not found" error that was buggin us from the beginning! After searching, mailing, chatting en googling on what might cause the problem I decided to go over the redirection config once more and found a lousy /Main instead of /main pointer in the code. Seems like that little capital caused a LOT of trouble.
