fix mysql error and make buzzerchat working on this server

I have installed buzzerchat from [login to view URL] at this url [login to view URL] and if you try to open any chat room [login to view URL] it says **Sorry! :** Field 'user_id' doesn't have a default value and many other mysql errors and chat room redirects to homepage and shows many errors, its windows hosting - buzzerchat works 100% on linux hosting, you need to make buzzerchat working on windows hosting. You just need to fix this so that user can stay in chat room and chat room works 100% fine and his name is shown in userlist and text messages are displayed. ftp and phpmyadmin details will be provided upon request.
