Module refers to database table that does not exist

I have installed the module and associated dependencies. I get the following error message - it looks like the table prefix is not being included in the database query: my table prefix is bap_ and I have the table bap_node in my database, but not a table node.

user warning: Table 'dbname.node' doesn't exist query: SELECT nid FROM node WHERE type= '1' AND status = 1 in /drupal6/sites/all/modules/booking_timeslots/modules/custom_timeslots/custom_timeslots.inc on line 7

The module keeps requiring me to configure timeslots, but nothing I seem to do works. I have also tried the 1.x-dev version of the module with the same error reported.

Note sure if this is a 'bug' [in which case it is critical] or if I have missed something in the installation. Any help/guidance would be much appreciated.
