Hi Craig,
What might have happened is that Quick Fields was re-installed on those machines at some point and the installer was told not to use the existing registration for the license (so a new instance was registered). This can be remedied by opting to use the existing registration when installing. You can find which license is active by opening the LF.licx file that Quick Fields is using and looking for the "InstalledApplication Guid" inside. This will correspond to one of the Application GUIDs in LFDS.
Which version of QF are you using?
