Hi Leon,
I'm a bit confused what you did there, but:
- You need to operate only one BIMcloud Basic if you wish to work together,
- You need to agree on a common Archicad version, both major build (e.g. v23) and minor build (e.g.3008) should match,
- You need BIMcloud Basic since you are students and most probably have no BIMcloud User License,
- To be able to Downgrade, you must log in as a masteradmin, else it won't show up as an option.
Kind regards,
