What could be wrong?

var itemEquip = new MsgItem { Identity = item.Identity, Action = ItemAction.EQUIP, Param1 = (uint)item.Position };

            // We build the item information packet
            MsgItemInformation itemInfo = item.InformationPacket(!isLogin);

            // If we are logging in, we set this as default, because the item hasnt been
            // created yet, otherwise, we send this as an update.
            if (isLogin)
            {
                itemInfo.ItemMode = ItemMode.DEFAULT;
                m_pOwner.Send(itemInfo);
            }
            else
            {
                //itemInfo.ItemMode = ItemMode.Update;
                if (!m_pOwner.Inventory.Contains(item.Identity))
                    return false;
                Item trash;
                m_pOwner.Inventory.Items.TryRemove(item.Identity, out trash);
                item.Save();
                m_pOwner.RecalculateAttributes();
            }

            m_pOwner.Send(itemEquip);
            Items.TryAdd(item.Position, item);
            SendEquipedItems();
            item.SendPurification();
            item.TryUnlockItem();
            item.SendItemLockTime();
