Dear Shi, the problem is incompatibility of the DM file as was previously stored with the new calculation. If you don't see an obvious reason why it might have occur, simply remove (or rename) your .DM file and start from scratch. However, starting OrderN from scratch can result in other problems, since it is rather fragile. If you can afford doing diagon for the beginning, it might be a good idea.
