Download Link for ArchiCAD 17 anyone?

[Gus]

I have to "save down" to ArchiCAD17 from 20. I have installed 19 and 18 and I have saved my .pln to 17 now, but I cannot view it in 17 to see the results, and I can't find a link where I can download version 17 anywhere. I found a page that seems to be the download page, but it says the file is "unavailable." I have an ArchiCAD Plus subscription, but there is a glitch in the "myArchiCAD" login for me which Graphisoft seems incapable of fixing, so I cannot access the 17 download through that route. I've always needed direct downloads instead. I can't find the ArchiCAD 17 direct download link anywhere though. Does anyone know where I can find this?
