Help with Lotus EasySync Pro (4.0/4.1)

Many of the users that I support have been running into problems synching from Lotus Notes (R5, 5.0.9a) to EasySync Pro (4.0/4.1) on a Palm unit.

Would anyone know where I would be able to gain more knowledge on Easy Sync Pro, or get support? excluding Lotus because they do not provide support for that product..

Thanks in Advance
Martin
