xD What about using google ?
First ,what are u looking for ? For example if u r looking for an Item and u know the item ID.
For Example the Item ID is "69"
Start Neocron/WPE and the the item(ID: 69).
Record this with WPE PRO .open it and Search for the value
69. With a bit of Luck

u just finnd 1 or 3 entrys.
Set a Filter up and edit the postion of the Item ID.
//For example there is
19 34 12 17 14 69
//Set up a filter and edit it to
19 34 12 17 14 79 (or the Item u want to get)
Run Wpe set a Trade or something like this while using the filter.
Now u should have the item with the ID 79.
THEORY , NOT working ! i think so ^^
Thanks recommned
