We are sorry but there is registration flow and we cannot change it.
It is described in the instruction included in the Give Away of the Day package:
1. Run Setup.exe
2. Run Activate.exe
3. Enter license number in the License dialog (accessible from G-Recorder tray icon menu)
It looks like that some of the above steps was not executed, that's why for some users G-Recorder remained in trial.
Please note that GOTD license has no free vendor support, it prevents installing G-Recorder after promotion day on another computers and has no free upgrades - these are official GOTD license restrictions.
sorry for inconvenience,
G-Recorder Team
