raisonance dongle security 8051 8052 c compiler

As the title say I want to buy Expansion Board 8051 Core System Board Single Chip Microcomputer. Is that worth buying. Here is more specifications: Expansion Board 8051 Core

I purchased the RKitL51 8051 C compiler from Raisonance some years back along with their security dongle so I could run it on a new PC if problems arose with the hard drive/motherboard, etc. It runs fine and does everything I need but for one little problem - the security dongle won't work...
