When I'm trying to get cjb mod into my minecraft. So first I have to make the minecraft.jar file into an archive, then I have to put modloader, and cjb into the archive folder. When I get that done, and try to login to minecraft it says "Can't connect to minecraft.net". But when I have the original minecraft.jar file it works. I am running on a mac.
Okay, Thank you, I am playing again with cjb. I didn't know if it was something with the cjb mod, but its working now so that's good. I'm probably not going to log off anymore, so I don't run into the problem again.
