I think you have been manipulated by someone, or at the very least, grossly misled.
There is no money in this. Certainly not enough to pay for lawyers. My advice is to not fall for this "legal" extortion scheme, whatever it is, you have already lost more than you can gain. SFC models cannot be sold. Period. If they are, then only the original licensors are entitled to any remuneration. If someone is selling your models, you are not entitled to any money, but they are obliged to pay Paramount, ADB and Quicksilver the appropriate fees, which I can guarantee will cost more than they have made.
Dynaverse.net is not involved. Let's make that clear at least.
