Sample Company Data restore error in GP 2013

In GP 2013, I have creaded a sample company with DB name TWO1 and then created another company, Sample Company 2 with DB name TWO2. In order to have some data in Sample Company 2, I have restored TWO1 over TWO2. Now I get following error in logon window:

" The selected company is not configured as a company of the current Microsoft Dynamics GP system database. You must resolve the database configuration to log in to the company"

I appreciate your help.

Thanks.
