Help!!!!!!!

Zac im a mod and im in dev.team i seen people on the server but every time i try to get on i get a communication error.

Are you 1.3.1? Because craftbukkit has not updated to 1.3.1 so you must downgrade to 1.2.5 play for now.

Zac how do i downgrade from 1.3.1 to 1.2.5

Download the 1.2.5 jar here

If you can't find the link on that page use this:

[Only admins are allowed to see this link]

Once you've downloaded the .jar go to you Minecraft files, which can be found

c:/users/(your username)/appdata/roaming/.minecraft/bin

Should be found there if not press the start button on your keyboard (or the icon on the bottom right of your monitor) and in the search box type, %appdata% then click Roaming then click the .minecraft folder and then go to bin. Once you have the .jar delete the 1.3.1 .jar in that folder and replace it with the 1.2.5 jar you downloaded.

If I wasn't to clear in this, just ask questions and I'll help best I can

Edit also what does the message say exactly? Is it just something to do with the server running on 1.2.5?
