AVG User interface has stopped working

Got message when i start my laptop AVG User interface has stopped working.  How do I get it to work? I have reentered my license number and it still doesnt work.

Hello Debbie,

Sorry for the inconvenience caused.
May I know the name of AVG program for which you are experiencing the issue?
Also mention whether it is free, trial or paid version.
Do you get the message only as AVG User interface or do you get any error code along with it?
