lost contacts upgrading to version 7

The contacts in a personal folder were not migrated when upgraded from version 6 to 7.
I created a ticket, but already 2 weeks waiting for a o real answer.
How can get I my lost contacts back, one can seemingly only import mails…


Today also i bought version 7 lifetime uprades, and after upgrade version 6 i lost all contacts !!!
it was very important contacts! it looks like emclient does not treat serious customers!
