Ok guess it wasn't the same wp prefix error then....
um... well no-one else has reported this error, so it has to be something specific to your site. To fix it, you first need to identify (isolate) the error. Work through the normal steps:
- disable all other plugins
- try a theme we know works (like twentyeleven)
- try deleting then re-installing the plugin
- run a JS debugger to try to identify any error codes
Basically the error message you've posted shows it can't find the playlist table in your database. Failing all else, I'd suggest you manually go into the Database via PHPMyAdmin and delete it... then re-install the plugin and see if it can create the playlist properly now that the wp prefix issue has been sorted out in version 1.6
Let me know how you go...
