Thanks for being of a bit more support.
I guess Magic Launcher couldn't tell that InGameInfo XML was for 1.5.2, put in the 1.5.1 version and Minecraft boots up just fine.
Apparently I was not clear enough. I am using the 1.5.1 minecraft jar, all the mods I have are for 1.5.1 and forge is on the latest version for 1.5.1
Why would you say to update to 1.5.2 if I stated in my post that I am trying to play on a 1.5.1 server?
I went to load up Minecraft on 1.5.1 because the server I'm on is still at 1.5.1 and I got this error.
Mods Im using in picture below. Not sure why, but I ALWAYS get the 1 errrors message with forge, yet it works for me.
Here is the log you need, I think.
