Having problems creating or editing items

[_OZZY_]

I'm using EqEmu 0.5.3-DR3 with the mw_052_053_alpha2 database. When I create new items (using a new ID) with the ItemEditor 1.6b, everything appears to go into the database correctly, as a query in MySQL shows the item. Yet, when I summon the new item I get an item not found error. When I edit an existing item (1001 Cloth Cap, for example), I get the original item instead of my edited one. Thinking that maybe the ItemEditor was the culprit, I treid the same using MySQLFront. The results are the same. I'm sure I'm forgetting to do some minor thing, but I'm lost at the moment. Could someone be kind enough to give me some pointers? Thanks in advance.
