Repeated error message (Possible repost)

Ok so hit the play button, Loaded up the first time. Exited it to try and download ender's since I remember that being the preferred client back in the day. Couldn't figure out enders so left it alone. Now It wont load at all. Will start up when I hit play then give me an error and shut off. I changed the Java 7 deal for allowing sites etc, But that may not be the issue. I'm pretty bad at this, Ended up having to get a friend who played to explain it to me.

With out the content of error message it doesn't make much sense to post

Also : are you playing because your friend helped you to make it run?

My apologies about the late post, I work night shift so on at odd times. Anyways, The friend in question ended up pointing out to me what I did wrong. I'm apparently worse at this than I thought

Here's the message upon using the regular client. Not sure how she fixed it and not sure if it will happen again so if you get the chance to elaborate on it I would appreciate it.
javax.media.opengl.GLException: haven.GOut$GLException: GL Error: 1280 (invalid enumerant)
Caused by: haven.GOut$GLException: GL Error: 1280 (invalid enumerant)
Shortened it but if you need the full thing I got it saved on notepad.
