Problem when changing ISP

My old ISP supported Access 2002 databases and I therefore use the access 2002 version of the database. My new web space provider though supports only access 2000. I converted the Database using MS Access 2002 to Access 2000 file format. Now everything else in the forum works except the file default.asp. Everything else works really fast but default.asp gets a timeout error after a long time. The database is quite big, about 30 000 posts.
