Open .json show data on colorsource40 (3.0 and later)

Ive been googling about this and found the following on , wich does not make much sense to me:

https://support.etcconnect.com/ETC/Consoles/ColorSource/Software_and_Programming/Import_.json_File_into_v3.0_and_later#

Import .json File into v3.0 and later

...but then it says:

"To Import the show format .json from ColorSource Console Software v2.6.0 and earlier the showfile has to be placed in the following directory:

Drive              Folder        Folder               File
USB (E:)         Shows        Showname        Showname.json

The path in explorer will look like this:
E:\Shows\Showname\Showname.json

After loading the show in v3.0.0 and later you can save the showfile as usual."

i tried anyways but getting an error message loading the .json file. For me the last sentence as well as the tile clearly state that it should be possible to load json show data post 3.0 ...although the earlier sentence says 2.6 and earlier... confusion. Is it possible or not? if yes, what am i doing wrong?

Thanks!
