I use ubuntu (latest LTS release). I pay for my account through Steam. I use the installation file downloaded from ryzom.com. There is no reason to have a CSR separate your account from steam.
When installing on Ubuntu you need to also make sure you install the appropriate 32 bit drivers. Ubuntu default is 64 bit these days which can be problematic for older games. Try running Ryzom from terminal to see if any error messages appear to help determine for which drivers/libraries it might be trying to open.
