Dave might I suggest 2 solutions;
a. Find if the Wouxon you have has a Yahoo group - chances are someone there is having a similar issue
-or-
b. Use Chirp (it too is freeware) - it doesn't use the ARRL directory, it uses either RFfinder or RepeaterBook - and, as a bonus, it even has a minor capability to import from the RR database based on zip code, a little like Home Patrol. The RR import is not particularly complete, but you might see if RepeaterBook or RFFinder has what you need.
You didn't mention which Wouxon model you're using, but here's the home page

The support forum (very active)
