I am unable to get the link to open. I chose "save as", saved it to desktop, then opened it and all I see is a garbled text document. If I select "open", it opens the same text document. I have installed and used the other chroma key software by "mgeorgiady" and it works fine. I see that one other person had a similar zip file issue, but there was no resolution. I am undoubtedly missing something, probably obvious, but regardless, I am unable to install the plug in. Any thoughts or help are appreciated.
