Description of Problem:

When I try to open up my Start.command file it gives me this message I have never had this problem before I updated it, my client works fine. There is an update to get me to Update 21 but I believe if I update it, it wont let me start the client.

Try removing the mod "Nether_ores" in the mods folder, i had a crash with it to, there probably is a fix for it but i just removed that, it seems to cause a error on servers for some reason

[MyCatFishSteve]
