There's probably a very simple solution to this, but Sprut isn't offering any clues.
I downloaded and installed the V5.50 upgrade to my PCNC installation a while back, and everything appeared to be fine. Now, however, I can't get into Sprut without it demanding that I register, and naturally it won't accept my registration key.
What's going on? I suspect I just need to move one of the dongle key files, but can't find any guidance.
A little help please.
