Bought 'Unlock all' - its all gone now – AmpKit - Guitar amps & pedals Review

I bought 'unlock all' in the app for $49.99 on 10/4/2014. App worked great, dug the models, used it regularly, all good. Stopped using it completely for a long time, have had two new phones since then, and tried to use it today. The free Peavey models work, but the rest of it - its like I never made a purchase. All my presets are there but none of the models they use are available. The app is pushing me to re-buy everything. I already gave them $50! Why? Left two support requests on their website today, haven't even received an auto-acknowledgement email from them - nothing. I have no idea what I can do to fix this, if anything. From reading other's comments here with similar stories, it looks like nothing unless someone starts a class action. If you haven't bought it yet, don't. Go buy something else that won't forget your purchases, from someone else that supports and stands behind their product.
