Suppalele

Dear all.
I have a very big problem trying to sync to server from SI 5.2.
I go to MMPD, Administration, LANSync.
I try "Synchronize now", but I get a message "You have not downloaded the MasterTable from LAN. Please do so first <cut>". I follow the indications and then press "CopyDown To Local". After confirming the next two boxex, I get a third with a progression bar "Connecting to LANSync Server Database..", and immediatly another one "MasterTable not uploaded to LANSync server by LANSync Administrator". I checked the Admin console on the computer (Windows XP pro) with the SI server, and the account I use is member of administration group. The permissions are all checked, except the ones starting with "Restrict ..". I also added an Administration console user with the same username/password of the account, but nothing.
I also tryied to use "Copy Up To Server". After confirming the deletion of the database, I get a window with a progression bar "Deleting All Product(s)" going to full blue, and a new message "Error in Object: CopyLocalDBToLANSyncServer - Error Description: The conversion of char data type to smalldatetime data type resulted in an out-of-range smalldatetime value. - Error Number: -2147217913".

HELP! What can I do?

If it could be helpful, I'm using a Win XP pro SP2 machine, and the settings are for italy (date in format: day/month/year).

Best regards
