Demo Content and Joomsocial 2.0.2

I have installed,
- Joomla 1.5.22
- Quay (1.1.1)
- Joomsocial 2.0.2

Imported:
sql_dump.sql

Quay gives error db:

500 - DB function failed with error number 1062
Duplicate entry '82' for key 1 SQL=INSERT INTO `jos_community_users` ( `userid`,`points`,`thumb`,`avatar`,`params` ) VALUES ( '82','0','components/com_community/assets/default_thumb.jpg','components/com_community/assets/default.jpg','notifyEmailSystem=1nprivacyProfileView=0nprivacyPhotoView=0nprivacyFriendsView=0nprivacyVideoView=1nnotifyEmailMessage=1nnotifyEmailApps=1nnotifyWallComment=0n'
What must I do to install the demo content?

Probably the demo content is for previous version of JomSocial, for JomSocial 2.0.2 we provide only update for gk_style.
