League won't update.

When I try, it gets stuck at 0% or 100% and I've tried at least 5 times, 3 times this morning and 2 times now. This morning it got stuck at 100% twice and another 2 times it got stuck at 0% and just now it got stuck at 0% but closed on its own before it got anywhere. Edit: After the last try I restarted League again and it finally allowed me to login and let it update properly (I hope)
