Problem logging in to my ClinicOffice Database

Hi. i have a problem login in clinicoffice in my computer since the 23/5/2014
The setup i have is 2 licences 2 computers and 2 users. The primary computer shares the database in a wired network to my 2nd computer.
Both computers windows 7.
The problem is that clinic office thinks that i am already logged in my second computer and does not allow me to login.
I open the user session manager from my primary computer that hosts/shares the database and i try to force remove me from the list on the 2nd computer.
It does not work it cannot remove me and i am stuck..
After 7-8 days and although the i power down both computers for hours it is still stuck thinking i am logged in.
regards
Maria.
