Trello Exception when getting private data from previously authorized app

[VisualBean]

It might be me that's doing something wrong.

I authorize my app and get the token and so on and so forth - works 1 first time around.
2. time around, I do nothing, as my app is already authorized.

I've tried storing the token for later, then reauthorizing my application, same problem occurs.

I've noticed that every so often, I have to re-authorize IFTTT with Trello for recipes to continue working. I wonder if that's related.
