Okay weird issue here
Tried to launch a game but my laptop crashed.
Restarted it, tried to open the League Client and, for some reason, it had changed from EUW to NA and seemingly forgotten all my login.
I changed it back, logged in and the game loaded but it crashed again.
I reset my laptop for the second time and now League won't open at all.
I click it as admin, I see the circular blue loading bar next to the pointer and nothing.
It won't open and it refuses to open no matter what I try.
I don't want to reinstall it if I can avoid it. Takes too long to patch a fresh League with my connection...
