That is strange. Please try another of the Newfangled wizards, like copy cat or drillwiz. Also try another non-newfangled wizard. I want to see if this is wizard specific or a mach issue.
Actually, the wizard code never looks for the license, that is handled by mach when the wizard exits, not on startup, so I dont see how adding a license would stop the wizard.
What if you remove the license files from the c:\mach3 folder? dont loose them, make sure you have a copy somewhere else. Try removing wizlic.dat first, restart mach and see what happens. No need to re-boot, just a restart of mach.
