We have updated firmware version now.
Please download new firmware version here -

Upload firmware to  printer in normal mode  - dont put printer in Program Update mode -  the printer will restart , but the firmware won't get 100% - about  80%  -  just close it in task manager

Then use License.exe
Please reply about results.
