Hello. Firstly please respond in simply english beacause my main language is polish.

I got a problem with AVG IS. I bought a product key and registered it but after about two weeks AVG doesnt work correctly. Actualy - completly doesnt work.

When I turn on my computer, I see information "You have to correct product key" so i type it. Then I see information that code is ok. But a few seconds later AVG stops working. Apears the information: "Program AVG User interface stop working" and the small text under that. The only thing I can do is "close program". Avg turning off. But when I want to turn off again I see the same information and problem is still not solved.

Im using Polish version AVG IS. 
Windows 8.1.

I beg You for help as soon as possibly but now a dont have any security on my computer. Is denger.
