Welcome to the forum Igor,
I'm sorry to hear Carcassonne 2.0 doesn't come with the River, how strange.
Unfortunately, to scan and upload the tiles with the original published layout for the community, is against the law of the copyright conditions.
We are allowed to create our own landscape tiles with different layout than the official published tiles, but we are not allowed to upload original landscape tiles, so long as they are not for commercial sale.
I believe there are scans elsewhere (BGG) if you look.
