? hmm, no IP and MAC shouldn’t be in your license files I think… if you place a space wrong in the licensfile, the file is corrupted, maybe that was your earlier problem? You shouldn’t touch or alter the file, at least, there is no need for it. The security uses the info from the file, but the actual verification is off course done on my license server, so changing expiration date in your file, won’t have the effect of an extended license ;-)
