League client isn't starting

When I try to open my league client it shows the league of legends logo but it wont start the client. What's weird is that after opening and closing it multiple times it sometimes does work, however ive been trying for like 10minutes now and still no succes. I have tried administrator and ive tried to reinstall but it didn't fix anything.

We're testing a new feature that gives the option to view discussion comments in chronological order. Some testers have pointed out situations in which they feel a linear view could be helpful, so we'd like see how you guys make use of it.
