I want to run DX4WIN 5.03 on 2 Computers. One for HF and another for VHF/UHF. The one for HF runs ok since 2 years. Now I installed the Program on the VHF/UHF-Computer but can't do the regstration. Everytime I type in my License-Info a window tells me that there is a fault and that I should try again. Must I have a license for every Computer i am using or what's the fault I do. 73 Sven DL8HCO
