Incomplete support, app that won't allow access to my files – Voice Recorder+ Audio record Review

I've owned the "Pro" version of this app for some time (despite the iTunes store telling me I don't have it), and it has been installed on my iPhone 4s. It worked, at some point, and I recorded a bunch of things I want to remember, with it. It will no longer run, however, on my 4s. Starts up with an error about the audio device. I've contacted the developer multiple times about how to record my voice recordings if I can't start the app - but I guess the language barrier is preventing him from getting me clear instructions. So my attempts to use this as a memory aid just resulted in me LOSING lots of stuff I wanted to remember...
