AVG doesn't load

Hello Dominique. Could you please let me know if you are receiving any error message when you try to launch AVG or AVG PC Tuneup?

I click on the icon "AVG" and it doesn't do anything at all ! 
Every evening I do a PC Tune-up, but I can't get there anymore today ?
What's wrong suddenly ?

Thanks for an answer ?
