WHY DID THE BOARDS AND CARDS DISAPPEAR AFTER THE FREE TRIAL, EVEN THOUGH THE NO. OF BOARDS ARE LESS.

[FastXe]

I started using Trello and had just 4-5 boards and each of them had cards and information on them. after the free trial was over all the saved information disappeared except for the just 2 boards and the information very few information inside. This happened even though the total boards were lesser than 10 which is a limitation for the free version of this app. how do I, retrieve this information?
