The software could be very good, if the update function would work better. Already in the last version WISO control passbook 2013 worked the update does not, so I sit down with the Technical Support department and I had to download a new version of me. This time it's a little more complicated: the same error during update after I contacted the customer service department, referred me to this my customer, where supposedly a download is available, but non-existent. Now I have again written a mail to the Customer. I just wonder when I have an error-free version.
