Ok, so we will try to recover what we can.
In that folder I told you to copy, Go to the Designer Folder and then Temp; should look like this:

Look for the most recent file (or around the time when you lost this), you can see my most recent file is the "jlh..."
Inside, you should have one called script.robin
Open a blank notepad file, then drag the script.robin file into the notepad, and that should open it. If not, in notepad, go to File -> Open, navigate to this same folder and open the script.robin file.
Here, you should see the underlying code for the flow. Example:

"FUNCTION" represents a new flow. You can only copy one subflow at a time.
So, if you see a "FUNCTION" line, create a new subflow in PAD, call it the same, and then everything below FUNCTION to END FUNCTION, copy that and paste the text in the subflow...you should see all the actions pop up. You may lose some UI's or images, but the actions inside of each subflow will be recovered.
