If you continue to receive a MySQL create table error, even after using jPFChat v2.0.0 RC1b or later... and even after you've changed the chat to use the FILE cache instead of MySQL, then unfortunately, we can't do much for you at this time.  

We're looking into it, but your MySQL settings are preventing things from working properly and we cannot offer another solution to help until we have time to delve more deeply into it.
