The latest release is 2.0.1, you're quite a few versions out of date. I can't guarantee functionality in older releases as the purpose of updates is to fix issues and implement new features; it's the risk you run using single purchases as you are given no updates.
Releases are often made because Facebook changed the API on me and I had to implement the new usage; this is completely out of my hands in that regard. If you purchase within 1 or 2 weeks of a new release then I'd have no problem giving you latest, but your purchase is 7 months out.
