"Object Method Failed" with syncing GW 6.5.7 calendar

Using Tungsten E2 with GWPDA connect version 1.0 for GroupWise 6.5.7 6/27/07.

Having trouble syncing the GroupWise calendar items. Using GWPDA connect and choosing the "Combine both Palm and GroupWise records" for the sync. Receive "Object Method Failed" each time. Unable to complete a sync.

Is there an updated version of GWPDA connect for GroupWise client 6.5.7 that fixes this problem? Or any other suggestions would be helpful.

Thank you!
