Nevis Financial Regulators posted this warning on May 1, 2015, and as I recall there were warnings posted here on ET:

Hopefully the Nevis Regulators will be of some help, as there's probably some type of paper trail. Perhaps you can send a demand letter to their registered agent where the LLC paperwork was filed.
Best of luck in the recovery of your funds.
