Anti-virus and Firewall

I am running XP. I have no other anti-virus  program. I have AVG 2015.

It  worked fine until yesterday. I have 2 problems.

(1) "Firewall Stopped"- Clicked on it-message- "File and printer sharing disablerd." Clicked on Fix Now-Error message-"Could not finish automatic state repair. Clicked on change-nothing changed. Clicked on reset to default-nothing changed.

(2) "Computer not protected"- clicked on it. message-""Anti-virus partially protected." Message at bottom of screen-"Resident shield component not active." Clicked on Fix Now- error message-"Could not finish automatic state update."

What do I do?

Thanks
