Facing Difficulty in Login

I presently Installed VerintCommunity-12.1.3.23006 in my local machine. I followed all the instructions as mentioned in the user documentation to How to install. I added my admin credentials in the sql also using this script 

EXECUTE[dbo].[cs_system_CreateCommunity]
    @ApplicationName = N'telligent',
    @AdminEmail = N'admin@lenovo.com',
    @AdminUserName = N'Admin',
    @AdminPassword = N'[Admin]',
    @PasswordFormat = 0

When I try to login using Username : Admin and password : Admin It shows ''Invalid Credentials" error message. What would be the cause of it
