Got this error after I logged in and selected the 'Download' link. I also received it on a few others. I am running Nukes on Mysql 4.0.
org.jboss.deployment.DeploymentException: Error while creating table nuke_downloads_ratings; - nested throwable: (java.sql.SQLException: Invalid argument value message from server: "Too big column length for column 'comments' (max = 255). Use BLOB instead")
