Im Frustrated

So, for the past few months, Ive been using this glorious app (a 5/5) for my edits. I didnt think anything of it until today when I went on the app. I already paid the $6.99 for all the added stuff and tbh, I dont exactly go out to buy iTunes money often. So it irritates me that I now have for some reason lost my added features. and it expects me to pay another $6.99. are you serious!!! Has anyone else had this happen to them? I love the app religiously, dont get me wrong, Im just really f**king p***ed
