This is a simple fix for ERROR 0
Using a EP4.5 Database got a few errors (such as Item mall and some NPC errors)
How to fix this?
1) Open your database with SQL
2) Expand PS_GameData > Programabilitys > Stored Producers
3) Find "usp_Read_Char_Product_Item_E"
4) Right click and "Modify" (should open a page)
5) Change the last line saying:
SELECT Slot,ItemID,ItemCount FROM PS.DB01 PS_Billing.dbo.Users_Product WHERE UserUID=@UserUID
INTO THIS:
SELECT Slot,ItemID,ItemCount FROM PS_Billing.dbo.Users_Product WHERE UserUID=@UserUID
6) Execute (Press F5)
7) You are done, try opening game now.
The reason this happens?
The game does not run on a PS.DB01 USER but it runs on your LOCAL user that is why the Item Creation BUGS
