This page on the framed Tesseraction Games Website (thanks Frans) has word that the developer of Enigma is suing U.S. publisher DreamCatcher Interactive for breach of contract and racketeering:

Tesseraction Games has filed suit for breach of contract and racketeering against publisher Dreamcatcher Interactive. The lawsuit cites unpaid royalties, fraudulent sales reporting and intentional contract violations damaging Tesseractions intellectual property. Tesseraction is also seeking injunctive relief against the publisher. Are there actually any honest publishers in America?
