I crash when I join my server?

I know this probably belongs in the tekkit Bug Board but I have "insufficient privileges" to post there and I need help. I created this account (didn't have one) just to get help with this.

I was looking in my log and this caught my attention, although I'm not a programmer so I don't know what it means.

2012-12-28 22:47:24 [sEVERE] A critical error has occurred.

This happened after I created a quarry. I set it running with steam engines, went to brush my teeth, and when I came back to the computer two minutes later I had whitescreened. When I join the server it spawns me in for about one second, and as soon as it seems to load the area where the quarry was (I can see the chunks loading as I'm on a poor quality computer) I crash. I'm running Tekkit 3.1.3 on a Mac if this helps.

Help anyone? :(
