Beta9 crash on Fulltilt during auto-import

PT3 crashed last night during my HH auto import so I just left it down and finished my game then shut down for the evening(had some 600 HH imported at time of crash). started up Fulltilt this morning and as soon as i turned on auto import it started importing duplicate HH's from last night. How do I stop all these duplicate files? Or just let it run & dump them later. thanx
