Hate to tell you, but you may have to upgrade again... if you're holding PBP version 2.40 then you're about four/five years out of date... features have been added, issues fixed, and support for the 18F's added. v2.40 only really supported a small handful of 18F's. Go to the MeLabs website and look at the version history to see what you've missed out on. Most folks that use software seriously (rather than sporadically for a hobby) would upgrade once a year or every couple of years at least, and $25 every couple of years (equivallent to $1 a month) dosen't exactly break the bank if you've paid out $250 for the product to start with.
