AVAST STOPPED WORKING!!!!!

After I updated the product, avast stopped working!!! I’m not protected!! what must I do??? I still have 3 months. whats going on???

what means “stopped working”? Any message? Screenshot?

http://forum.avast.com/index.php?topic=107218.0 ok I managed to fix it. worst thing is I don’t even know when it stopped working after the update. This clearly is not my fault. I don’t think I’ll be renewing my subscription. I can’t deal with this kind of drama
