When I try to open adventurecraft.jar for minecraft 1.2.5 on my mac it says the file cannot be opened, check the console for error messages
it tells me it cant open the file and check the console for possible error messages. i down loaded the most recent adventurecraft and I have MAC OS X 10.6.8 and I have the most recent Java for 10.6.8, but it wont open the .jar file. I am really getting angry at it because I cant seem to fix it! Please Help!
