I need to start off by saying that I am not particularly computer literate, so please be gentle. I was trying to find a customized invoice which I had saved in my accounting program. I thought I had found it and wanted to open it to see if it was the one I needed. I was asked to choose a program to open it with and I chose Acrobat, as I just wanted to see what it looked like. That file now only seems to be able to be opened in acrobat. How do I revert it back to it's original form, so I can upload it into my accounting program to use. Thanks in advance.
