You can use the LPE (LimeWire Pirate Edition) which seems like LW Pro when it's used. It connects to same no. of ultrapeers.

Otherwise, depending on your OS platform, it is still possible to run LW 5.5 Pro on your system if you previously had 5.5 pro on it. However, LPE connects much much easier. LW itself tends to have connection problems.

And no, not possible for a refund for two reasons. (i) The company never gave refunds & specified their reason after purchase in their small print links (ii) The LW company is not dissolved but no longer operating as it was. They would not choose to deal with such issues now; ie: they canceled all Pro registrations late last year. (A small chance you might be speaking directly to a RIAA representative even if you did email them.)
