Price List Add On PDF Results EMPTY

When I try to run the add on on it produces no results and makes an empty pdf file.

Is there possibly a setting on my VPS that is causing this issue?

Anyone have any ideas? I'm using CS Version 3 RC 5.

I have tried the same thing and sometimes is just quits and never finishes. I was wondering if it was my hosting timing out. We are currently using godaddy shared hosting. I just assumed this was the problem.
