need help for a W3dota app.

[acarrunto]

ok I don't know if this post belong in this section or another, this is my first time here , well I'm here because i need your help, I still play w3 dota map but a few days ago in the server i play, a new map came (6.88t) and it came with a lot of nice changes and one of them are the new items, so i thought I could make an app that could teach new players to learn or remember all the items used in the map, and that is my first problem, i don't know how to extract all the items icon, I tried to open it with my world editor but every time i do it an error always appears.
