Sorry if I came across in an accusational manner, but there are a lot of people out there looking for "cracks" to avoid paying for the software.
Unfortunately if one actually loses the hardware, dongle or Tx interface, sadly they are SOL

, if it's damaged or inoperable contact Ikarus, they have policies regarding replacement of cables that are inoperative or got chewed by the pet Tarantula[X(], but y'gotta have the "remains"
I believe there was a thread some months back where folks in Euroland were being prosecuted and fined for buying illegal interface cables on the internet, sounds a bit draconian to me, but the market for r/c flight sims is nowhere near the size of any other game or simulator, so the software folks have to protect their investment.
