[Crash] Game Will Not Load. PC.

So I get into a ranked queue as Nautilus top. This game looks promising. But then, during the time that it would normally load, I just get a black screen with my regular (not League) mouse pointer on it. So I Ctrl-Esc, because I have had this bug before, and normally I can just do that and then click back into the game, where it will say a message about the connection failing, and I can then click on "Retry" and it will load. I never reported it before because it only slightly affected me. This time, however, it did not let me click back into my game. I kept clicking the League icon, but nothing happened. So I decided to restart WTFast (which was actually the source of the bug) and of course that took a while, but when i had restarted both WTFast and League, it still had the same bug and did not let me reconnect. This had happened to me before, so I just restarted my computer. When the restart was complete, I once again went through WTFast into League, and it worked at last this time. So I was finally in game, 4 minutes in. However, it lagged the whole time!!! After a while of laggy but manageable play, I disconnected again!!!! This time, I had to restart my computer twice before League worked, and it only worked when I did not use WTFast. When I got into game, my team was of course irate, we lost the game, and now I have 5 delayed queues. Please fix this Riot, I do not want this to happen to anyone else!!!
