PBP Version 2.3 is probably well over six years old (it's time MeLabs put a Date against the version releases on their website) and has many issues that have been fixed and improvements made over the subsequent years. You should seriously consider upgrading. Forum members here would be hard pressed to try to second-guess problems when you're using a product that old and you could spend many hours chasing a problem that has been long fixed and forgotten in the mists of time.
