Unable to make local calls with magic jack 928 area code

I can call long distance and cell phones but can't complete local calls - after 8 rings the system just reverts back to a dial tone.

This is the fix that was offered to me after hours of running through other options:
Harold: First right click on the one called "MagicJack" and then select "Change Drive Letters and Paths". In there select "Change" and then use the scrolldown menu to select "X". Click ok, you will get a pop up asking you to confirm, press yes.
Ed: done
Harold: Cool..
Harold: Now do the same thing with the drive called "phone". Name that one "Y".
