Session problems

Hi there,
I've installed the module is it seems to be working correctly. I only have 2 problems.
1. My session does not transfer between my two sites, I have to login again
2. After logging into my default website, then refreshing my muiltsite 1 I get the following error messages:

    * user warning: Table 'mydatabase.sessions' doesn't exist query: SELECT sid, uid, hostname, timestamp FROM mydatabase.sessions WHERE sid = 'q8ioldg8h0j7qemhmr9bar1ao4' in /home/www/sites/all/modules/multisite_login/multisite_login.module on line 419.
    * The session q8ioldg8h0j7qemhmr9bar1ao4 doesn't exist on the originating site: SELECT sid, uid, hostname, timestamp FROM mydatabase.sessions WHERE sid = '%s'
