Hi there
Two possible reasons for having a disabled save button:
1 you have not yet entered your user name and registration code into LEAP. You need to do this once you have been sent these on granting of your license. Enter these using the Help: Register menu option in LEAP.
2. You haven't made any changes yet. The save button only becomes enabled once you have made some changes.
Hope this helps - please do let us know.
Best,
Charlie
