Contracts - Date error when importing xls

Contracts - Date error when importing xls

Hi,

I get an error when trying to import an .xls-file into the contracts module.
I read in another thread that the cells that holds the information about the dates needs to be formatted correctly for the import to work, and i've tried formatting the cells but i still get the error. 

SDP 9305, MSSQL
