## USB HASP License Activation Troubleshooting


If the ***UNIGINE 2 Editor for Sim*** card displays the ***Activate*** button and the *Requires Activation* text (as shown below), it means that SDK Browser failed to detect the inserted USB HASP device.

In this case close SDK Browser (and make sure that it doesn't run in the background), re-insert the USB HASP key into a different USB port, and run SDK Browser once again.
