QUICKBOOKS HEADACHE

I installed quickbooks 2003 pro UK version realease version 2, five user on five machines on a local area network supporting star topology. The installation was smooth and i had no problem with the installation keys or using the software in multi-user mode. The problem arose during registration, since i had only one registration key which i was made to bliv should register on all the machines without any hassle but the registration only registered on one machine and is giving an invallid registration message on all the other machines and leaving me with only 14 uses on all the rest, the QB help desk are asking for money which i dont have, could anyone be having the registration keys or an idea of how one can go round this registration headache. PLEASE I WILL APRECIATE ANY HELP.
