Santos,
First off; Have you called the folks at tech support and asked them all the correct questions to see what they have to say about it? But, I've got a copy of the last version of Altapoint's PM program's manual which has a fairly interesting SYNC feature in it. The instructions are very detailed and many pages long; and obviously making sure you go in the proper order, step by step is key. I know you are a detailed and experienced user so I'm sure that you followed the directions as best as possible.
But, even back when this feature was in Beta form, I was requesting that AC post their own very detailed step by step set of instructions that one could review and digest BEFORE they started the whole process and I still wish they would now. Also, perhaps a conceptual out line of what is happening would allow users to have a better understanding of the entire process, and in doing such, there would be less confusion for all. As I've said before, a well laid out set of instructions can save tech support and users a whole lot of headaches in the long run...Let us all know how this turns out and thanks for the update.
Paul
