Hi
I'm not expert of oacs. The people here wil correct if i'm wrong. My shot is:
It seems there is something, a table or a relation that you deleted it but it's still there. Check "lang_messages"
query "insert into lang_messages" right on the top.
Now that you are trying to reinstall it you get this trash code. is the first time you install contatct pkg??
