So, up untill today there were no issues at all.
Out of the blue, the following issue came:
When I open up Google Chrome and I start browsing without logging in to LastPass, there's no problem. When I log in to LastPass, somehow my internet isn't working anymore. I open up a Google Chrome, log in to LastPass, go to gmail.com en log in, but it gives an error code saying ''can't syncronize with your account'' and then it just kind of pauzes. When I try to do anything else in Chrome, it just doesn't work. Wondering what's up...? Installed AddBlocker Plus yesterday, maybe that has something to do with it?
