Digisport software comes with a SINGLE USER LICENSE entitling the Registered User to 3 installations of the product. Each installation requires the Registered User to request a REGISTRATION CODE from Digisport so that the software may be used beyond the 21 day pre-registration period. This request MUST be made by using the process built into the program after it has been installed. After a period of 12 months from the FIRST REGISTRATION, additional registration codes may be purchased.
