Server error reports
Here are some of the errors I got:
After the game, I was told that the server was offline, and I needed to wait to see the game results.
After speaking with a friend, just idling on LoL, I received a message that said: 'Unknown error: If this error recurs, please contact technical support,' essentially.
Upon trying to log in, I get the 5 failed attempts followed by the 'read this knowledge base article' error, asking me to do the win32tm thing.
Hope this helps. Happy gaming.
