Please help, don´t get support to convert all file to cpr

I just had a frustrating experience with the steinberg support. I want to convert .all files to .cpr files. I wasn´t able to install Cubase SX3 on my mac. But then managed on my PC, but it doesn´t open the .all files. After a few emails, it´s clear: there is no support from Steinberg. I am pissed about that.
If there is anyone in the community who can convert these into .cpr I would be super thankful.
Here is the link to the .all files:

My mistake: I clicked open file instead of import
