Adding VST2 to the whitelist

Before running the clean-up script I tried erasing the contents of the whitelist which, as expected, left no VST2 plugins available. I then re-added the whitelist content and restarted Dorico but my Lexicon reverbs were still not visible or available. I then dragged the clean-up file into Terminal and hit Return but got an error message advising the clean-up file doesn’t exist - a screen shot of the Terminal message and the clean-up file is attached. I’m unsure what I can try next.
