Fix IP board forum synch problem with WordPress SSO plugin

I am trying to synchronize my installation of IP Board from [login to view URL] with WordPress. I've just purchased WordPress SSO plugin at [login to view URL] installed it on IP board, configured it as per the instructions, added API to the php file, uploaded to WP installation folder, added the roles, etc. All seems to be ok. This plugin replaces the default IPS4 front-end login/registration system with WordPress. The idea is that once I log in, I will be logged in IP Board Forum and WordPress by logging in just once. There are many people out there that has made it work, I just can't. Contacted support but no answer from them. I want to log in WordPress/IP Board and log in IP as well but I don't think I am doing it correctly because it doesn't automatically log me in. My WP installation is at [login to view URL] I added a link to the IP Forum at the bottom in a link called COMMUNITY that links to IP installation at [login to view URL] My problem is that I can't find where to log in using SSO so that it can automatically log me in IP. I am trying to use [login to view URL] but it logs me in WordPress backend and won't log me in IP Board. What am I doing wrong? Can you help with with it? This short 2 minutes video explains the problem: [login to view URL] Thanks in advance
