Problems with migration from old ticket system

Since we wanted the same Ticket ID numbers for our old tickets.

I manually added a new record into the database. Tracked down to what
commands that were written into the mysql database by request tracker.
And inserted all the tickets from out old system.

Thou this came along with some problems.
#1; I cant “Take” any of those imported cases. It says:
System error
