When trying to install the minecraft launcher 1.6.1, the blue bar won't appear and then when trying to login in into the 1.5.2, it says minecraft crashed.

This ticket is invalid as it relates to a modded or 3rd party client/server.

• Any non-standard client/server build needs to be taken up with the appropriate team, not Mojang.

• Any plugin issues need to be addressed to the plugin creator.

• This site is for addressing issues related to the base unmodded MineCraft.

So who is the plugin creator that I need to get help from?

How do we know ?
You have modded your Minecraft in some way...

This appears to be your mod, you should contact this person or remove the mod
