So I bought a tier 1 server from servercraft.co and I'm having difficulty with installing craftbukkit because I'm not all that tech savvy. I'll give all the details I can hoping for assistance. I have windows 7 x64 minecraft 1.6.2 I made a .bat and put it along with craftbukkit.jar 1.5.2 and then tried the new 1.6.2 and put it in the proper directory in the versions folder. I don't know what craftbukkit build is or how to find it and I'm currently on Group Manager if that means anything.When I switch server type in my McMyAdmin from Official to Craftbukkit it says it can only work on 1.5.2 and I cannot play it whatsoever. Do I have to downgrade?? Honestly and I apologize, I have no idea what I'm doing or talking about. Any assistance would be greatly appreciated. I just want my plugins to work as I can only play on the server as Minecraft Official with no plugins.
