Lets try the profile section!

Now, the red is the version we no longer want so we are going to click on it and change it! http://i.imgur.com/4JlFYg6.jpg

The purple check mark is OK to have, the purple circle is what you need if you wanted to allot 2Gb to minecraft.

The red circle is the old version of minecraft, the green being the version you want to use. Just select the version you want and click 'save' then 'play' It is NOT recommended to have this set on 'use latest version'! Especially if you have 'snapshots' turned on! If minecraft updates and serenity doesn't then there is a chance that you could be locked out of the server due to it being a older version!

And that is it! Hope this helps!
