Minecraft Forums

I am running Mac Os 10.5.11 Its pretty outdated yes, but its all i have for right now. I'm unable to play any version past 1.5.2 due to no compatibility, so i play on 1.5.2 servers online. As of a day or two ago i was unable to get online. I looked it up and searched but it seems like none relates to this specific error i'm having, I found a forum and it says to Re-download The game. i did and when i tried it again it said not downloaded and it wouldn't connect.. so i went to the site, (Which i can connect to) And i played the demo, it downloaded the files and that was that. I still can't play and i'm stumped.. anyone know how to fix this? Thanks in advance
