You think asking where or if you looked is an investigation? That's too bad. You paid for a license, but most of the people here answering your questions, like me, aren't paid. I'm just another user like you. People here will try and help and answer questions out of the goodness of their hearts, but like you, they have other things to do too. It's not their job or obligation to be here to help you. I also sometimes have questions I need answers to, and I try to be respectful of other people's time by researching the issue myself first before asking for help. I don't think that's anything special about me, that's something every adult should be expected to do. Some forums have rules about the types of questions you can ask, or about how you have to read a long FAQ before you post a question, things like that. But not here. The community here tries to help everyone, but it helps the community if people also try to help themselves.
I could have just ignored your question, but instead I chose to try and help you. My intention was two-fold: first, to assist you with this specific issue, and second to better prepare you to be able to find some easy answers for yourself in the future. Because that would both help you, and help the community. Luckily, because the word "JRiver" is unique, it makes it very easy to find solutions specific to this software using google. Good luck to you.
