Free Features Are Blocked

So I have AVG free protection. Not as good as PRO protection, but I can't afford PRO. Anyway, I am trying to run a scan with my free protection but when I click one the button to go to the window with the scan option the window comes up but everything is covered with an alert that says my trial-run of PRO protection has run out and recommends that I buy it. I can't get rid of this alert, at least as far as I can tell, so I can't run my scan. Help?
