If it continues to fail you can try a Factory Reset.
There is an access hole on the bottom of the OBI.
Press the reset button with a paper clip and hold until the OBi starts to re-boot.
If that fails to help you can open an OBihai support ticket here:
http://www.obihai.com/supportTicketFormAYou should be able to use the OBi without adding it to OBiTalk.
You just won't be able to configure it with OBiTalk.
I see by one of your previous posts you have a GoogleVoice account.
Log directly into your OBi with the Web interface to configure it for GV.
