Phone service works but no 911 info and no ads

[petrus]

My Magic Jack works fine on one computer but on my other computer (the one where I wish to keep my Magic Jack plugged in) The phone service works fine (including caller ID), but there is no 911 info displayed (it says "Not connected, No 911 info available") and no ads are displayed. I am connected as my phone service works. This is not a big deal but I would like to know why the 911 info and ads are not showing on this particular computer. I tried disabling my antivirus and my software firewall (using only Windows firewall) but it did not make a difference. Has anyone else experienced this?
