I already emailed them, they asked for screenshots, but tbh there is nothing to screen shot, its as simple as, I dragged file to app to be converted, app says loading, when it finishes loading, nothing appears in app, nothing actually gets loaded. So it would be screenshots of nothing. I told them this a week ago and have had no response. I NEED to convert a file so that I can sell it, I have not found an app that compresses my files small enough for me to sell them like this app. But given that support has not been very supportive, I am looking for one.
