I can't install apps or extensions on Google Chrome.?

Last night, for some reason all of my apps on google chrome got deleted. I really want to get adblock back because I get sick of seeing ads everywhere. But every time I try to install a new app on chrome, a message comes up saying "Network failed." I already tried resetting google chrome and doing a full system security scan on my computer but the message still comes up. Please help me!
