[Ingame Error] I cant add custom items i've made ingame

Okay, I got this problem now:
I've made an item (At Wow-v.com) and i downloaded it for the correct rev and executed it to my db without problems and then i logged on to my server and typed .server reloadtable items but when i tried to add it got an error saying that item XXXX is not a vaild item. And i checked anothers post with the same problem and sickboy told him to delete cache and restart server etc etc and I've already done that but it still doesent work!

I am using WHYDB266 and Arcemu 2001

Help please
