Hi,
no trouble Ron.
In Mach3 each licensed user gets one license file. You could copy it and put that into as many Mach3 PC's as you like.
This has indeed been a problem for NFS, with one pirate license file turning up on thousands of PC's around the globe,
none of which have been paid for.
Mach4 licensing is different. Each PC has a unique PCID, identity code. A Mach4 license is issued for that C only. If you copied
it and stick it in another PC it wont work. If you buy Mach4 you may have up to five actively licensed machines. If one of them
craps out and you buy another PC with a unique PCID, you go to the NFS website and release the old license from the PCID of
dud PC and get a fresh license for your new PC. You are allowed seven such license transactions in a two year period.
So it pays not to be profligate with them! Still should be plenty flexible enough for a hobby user.
