I have put a folder on my computer batch_rename. It is a version that requires only that you put the folder containg the app in you computer. You can run it from that folder. I ran it yesterday to rename a group of files. Could that have done someting. My scteen refreshed and so I think it maght have done something to my settings. This is the program:
