If you don't understand an error message, Google it:
was deadlocked on lock resources with another process and has been chosen as the deadlock victim - Google Search[^]
As you can see, you aren't the first to meet this problem, and loads of possible solutions are proposed.
So follow some of the links and read what they say first: we can't tell you exactly what to do becasue we don;t have any access to your systems or data!
