I seem to be having a problem upgrading to 6.1.5 from 6.1.4

Executing Script: 06.01.05.SqlDataProvider Error! (see 06.01.05.log.resources for more information)

Looking at the log file i can see ....

System.Data.SqlClient.SqlException (0x80131904): The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "FK_Blog_Blogs_Portals". The conflict occurred in database

I've rolled back to 6.1.4 for now, any help or advise would be greatly appreicated.
