I think you should be able to do this:
Sign into any one of the ladders where you currently have your Platinum Account.
Click on the My Account Tab
Click on "Add / Remove Leagues" on left side of page. You should be able to follow the rest of the steps to re-add that league.
However, if you still need additional help I suggest you use the following Premium Support link:

Happy Gaming :o)
