Problem using Metabase

Hi, folks. I've recently decided to use Manuel's Metabase instead of ADOdb as ADOdb doesn't support transactions for MS Access, however I'm getting the following error when running the sample code: Fatal error: Class metabase_manager_odbc_class: Cannot inherit from undefined class metabase_manager_database_class in C:\Inetpub\wwwroot\etrakFE\classes\metabase\metabase_odbc.php on line 13 Obviously this means that the metabase_manager_odbc_class is being defined before metabase_manager_database_class, thus throwing an error, but the problem is I'm not calling this manually, and have used the sample code exactly as it is in the manual. Here's my code: require("classes/metabase/metabase_database.php"); require("classes/metabase/metabase_interface.php"); $error=MetabaseSetupDatabaseObject(array("Type"=>"odbc-msaccess", "IncludePath"=>"classes/metabase"), $db); if($error!="") { echo "Database setup error: $error\n"; exit; } $db->SetDatabase("etrakADB"); Does anyone have any idea why I might be getting this error? As I said I'm using the sample code exactly as it is in the tutorial, and am not calling the metabase_manager_odbc_class myself. Cheers and TIA, Pablo
