lost "local folders" information saved in eMclient when upgraded to Version 7 from version 6

After upgrading to Version 7 I lost the ability to expand distribution lists.  I checked the forum and tried to setup my DL in the local folder as suggested then I noticed I lost information I saved to local folders in eMclient 6. How can I retrieve the information saved to local folders in eMclient 6?

are the Local folders not present or are they just empty? You can enable them in Tools>Settings>General>General section by checking the Show Local Folders option.
What data from Local folders are missing exactly? Mail, Calendar, Contacts?
What is your set language for Windows OS and eM Client?
