[Tool] Spectate Anyone!

I've tried it, it works, awesome software, if you don't trust the program, register a new user and use that with this tool.

This is a tool that allows you to spectate anyone as long as you know their summoner name. It requires an installation of LoL and an account on the region you want to spectate.
DISCLAIMER: I am not responsible for any problems this program causes you. However, you have my word that this program is not malicious in any way and should not cause any problems. Source code is available below.
See attachments for screenshots of it in action.
How to use:
1) Make sure your Java is up to date (minimum Java version is 1.5.0)
2) Download the files here: http://www.mediafire.com/?fp83zzps6t8u8t8 (zip file containing a jar file and a bat file) or http://www.mediafire.com/?fxolghqxo9glh2f (this version doesn't save your password unless you put it in config.txt as "pass=foobar")
3) Extract the zip somewhere.
4) Double click the *.bat file. (You may be able to run the jar file directly if you're lucky)
5) Fill in the required information and start spectating people! (see the last screenshot for where to find the client version)
Note: This program requires a valid login for League of Legends. If you're worried about account security, create another account and use that.
How it works:
1) This program logs into Riot's servers using the information you provided.
2) Then, it asks Riot for the spectate info for the summoner you want.
3) Finally, it starts the game client in spectator mode.
Is it safe? Is it legal? Is it a keylogger?
-- Yes it's safe. Yes it's legal. No it's not a keylogger.
-- If you don't trust me, the source code is available here: https://code.google.com/p/lolrtmpsclient/
It's not working for me!
-- Make sure you update your Java.
-- Run the *.bat file, it's more likely to run the *.jar file properly.
-- Check config.txt to make sure all of the information is correct.
-- If the client is just a black screen, then the players are still in champ select or the first 3 minutes of the game.
-- If you get the error "'java' is not recognized as an internal or external command..." first make sure you have Java installed then you need to add Java to the PATH -- see here and here
-- If you get the error "Wrong client version for server" then make sure you're putting in the correct version. See the last screenshot.
-- If you get the error "Unsupported major.minor version..." then you need to update Java.
-- If you get the error "An Authentication object was not found in the SecurityContext" when trying to spectate someone, then you got logged out. You can only be logged into the client OR this program, not both.
-- If you get the error "Game is not observable" when trying to spectate someone, then their game has an observer setting that prohibits you from observing.
-- Post here if you still can't figure it out.
Other questions:
What regions can you spectate? NA, EUW, and EUN.
Is there a limit to spectators? No, only practice game lobbies have a limit to spectators. Once a game is started, theoretically infinite spectators can watch.
Can you spectate any game? You can spectate any game except co-op games or practice games that have observers set to "None" or "Lobby Only"
Can you spectate the game of another spectator? Unfortunately, no.
Can you spectate games on the tournament realm? As of right now, no. If I get the connection information for the tournament realm, then I can enable it in this tool, but it would still require an account to use.
