Im getting the below error when creating a new campaign. I have the K2 component installed (not sure if this makes a difference). Any help would be appreciated.

500 - An error has occurred.
DB function failed with error number 1146
Table 'nscc.n8xiq_community_users' doesn't exist SQL=INSERT INTO `n8xiq_community_users` ( `userid`,`points`,`thumb`,`avatar`,`params` ) VALUES ( '138','0','','','notifyEmailSystem=1\nprivacyProfileView=0\nprivacyPhotoView=0\nprivacyFriendsView=0\nprivacyVideoView=1\nnotifyEmailMessage=1\nnotifyEmailApps=1\nnotifyWallComment=0\n' )

Can anyone please help me with this issue? can it be resolved? Is there are reason why I have received no support on this problem?

It seems odd that there has been no support for this component. Unless the issue is addressed then unfortunately I will need to post a negative review.
