Can't update my AVG programm version and Web shield

I've got AVG Internet Security 2016. Everything seemed to be fine until the last week. The problem is, AV module and web shield module alerts for updates. I do updates, it goes well, but still alerts are present. I think, it's all about programm version (engine or core of those modules), because virus defenitions are up to date.So, how could I update them, if my programm can not do it itself? And one more thing, I'd like to stay with my 2016like GUI. I prefer do-it-yourself style, and all of those newish modernish we-do-everything-for-you programm styles are really annoying.
Thanks and pardon my English;)
