I frequent an industry association.
Depending on the country you are in and the nature of the association, you may find that there are legal avenues you could pursue.
Typically, any organisation that takes in money has some sort of legal status and there will be a set of rules that apply. The first thing I would do would be to find that set of rules and take it from there.
Of course, the rule book may not help - your experience is far from unique. For instance, splits in sports can often result from a similar scenario - I believe Darts is a prime example.
