When selecting forums to track and clicking the update link button I get the following error:

System.Data.SqlClient.SqlException: INSERT statement conflicted with COLUMN FOREIGN KEY constraint 'FK_Forum_TrackedForums_Forum_Forums'. The conflict occurred in database 'blah', table 'Forum_Forums', column 'ForumID'. The statement has been terminated. at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream) at System.Data.SqlClient.SqlCommand.ExecuteNonQuery() at Microsoft.ApplicationBlocks.Data.SqlHelper.ExecuteNonQuery(SqlConnection connection, CommandType commandType, String commandText, SqlParameter[] commandParameters) at Microsoft.ApplicationBlocks.Data.SqlHelper.ExecuteNonQuery(String connectionString, CommandType commandType, String commandText, SqlParameter[] commandParameters) at Microsoft.ApplicationBlocks.Data.SqlHelper.ExecuteNonQuery(String connectionString, String spName, Object[] parameterValues) at DotNetNuke.Modules.Forum.SqlDataProvider.ForumTrackingCreateDelete(Int32 ForumID, Int32 UserID, Boolean Add) at DotNetNuke.Modules.Forum.UserSettings.UpdateTrackingORWhatNewForums(DnnTree objTree, Int32 CheckType, String OriginalValues) at DotNetNuke.Modules.Forum.UserSettings.cmdUpdate_Click(Object sender, EventArgs e)

Anyone Having a similar issue or know the cause of this?

Thanks,
