OK, I could reproduce the error. How did you get your topology files?
 They look like they have been created with chamber, but maybe you changed
CTITLE to TITLE at the top?

Chamber files cannot be used with (and simply changing
CTITLE to TITLE at the top will result in broken topology files being
created with By changing CTITLE to TITLE, you have
