So clearly you have broken the file format, probably of at least atomtypes.atp. However we can't guess how if we can't see your changes (e.g. use the diff tool).

Also, you need to answer the last question Justin asked, because that answer is likely to reveal your problem...

    Did the program hang here?   Did it crash?  What modifications did
    you make, and to what files?  Are you using a plain text editor
    that properly treats newlines?
