“we followed the instructions and saved the script as a .vb file, exported the edl, and then tried to run the script, but when we were supposed to locate the script in the finder that opens up for you to locate the script, it wouldn’t appear.”
How did you save it with the new name?
Uncheck the “Hide Extensions” box in the Folder Options / View menu. I’ll bet that you renamed it to a .vb.txt file.
Open the file in notepad, then do a save as, but put the full name including the .vb in quotes. This will override the default .txt file type.
