Update:
If you have the "stream does not contain at least xxxxxx bytes" error, the approved fix is as follows:
- Open the Ryzom folder on your harddrive
- Make a copy of your \save\ folder so you have a backup
- Open the \save\ folder (not the backup) and delete the file "string_client.pack"
- Start the game!

Once you have verified that you can log in as normal, open up the backup version of the \save\ folder and delete the "string_client.pack" from there too
