Hmm ok "Unauthorized Access Attempt" shows when you visit the page you were not supposed to visit, so maybe there is a broken link somewhere that you clicked?
And it seems your session expires when switching between two our systems, most probably you somehow entered the state where you are logged in one system, but not logged in the other system (how you got there I currently have no idea). To fix that, you should logout of both systems and only then try to login back.
So try pressing logout in the Account drop down menu (which says Hello, Yourname!)
Then you can try login again (additionally you can check Remember Me for persistent session).
Also for security reasons, if website detects changes in client info (something changes in your browser, like some specific settings, or your IP address changes, or connection type, etc), you will be automatically logged out, maybe that is the reason?

But, if I click on "Pricing" on main menu my session expire.

Then verify that you are logged out in both systems by visiting:
http://giderosmobile.com/members and seeing login page
and visiting: http://members.giderosmobile.com/clientarea.php?action=products and being redirected to the same login page.
