"lol.exe has stopped working" This is rediculous

Every time I login to league of legends, I get a warning sign that reads "Disconnected from PVP.net". If I try to start a match, I get stuck with a "Retrieving Data from Server" that sometimes ends with "Connection Failure Error" or doesn't load at all, forcing me to exit the client and log back in. At times when I finally DO manage to enter a game, I get a "Disconnected from PVP.net Attempting to reconnect" in orange text that comes and goes. While it reads that, I can't click anything. Sometimes its only a few seconds, sometimes it never reconnects at all.

But the MOST bullshit problem the client has is during champ select when a window opens that once again "Disconnected from PVP.net Attempting to reconnect". This time, the text box NEVER disappears. The only option you have is to click 'exit' or x-out button, both of which logs you out of the game.

Note that this text box can appear at ANY TIME during champ select. So if you're playing ranked and this text box appears during champ select, you're practically screwed because you have no choice but to exit the client and dodge the game.

This problem has been going on for WEEKS now. Please resolve this problem as soon as possible
