Can't play the game???

I recently had this problem after re-installation for the patch (I have a mac), but the issue was fixed after I updated my computer software. However, it is back again. I can open the client, log in, select a world, channel, and my character, but as soon as I double-click my character, the client crashes. There is never an error message or anything, just the fade to black after the double click, which would normally lead to my char loading in the map, but instead MapleLegends crashes. This is a new issue as of today (worked perfectly fine last night). I re-started my computer and made sure there were no new computer software updates to be installed, but nothing seems to fix the problem?
