I am still quite new to this XML editing. trying to make my own UI, started out with just writing XML on top of my original downloaded UI yesterday, and came up with a result i really like. however that was for my pure melee, and I am tired of it now. so I just downloaded a new spell bar for casters (Xirinia) and I am going to make it vertical. However, I can't seem to make it work, at all.

the zip file i downloaded, consists of following files
CastSpellWnd.png (which seems to be an image file)
EQUI_CastSpellWnd.big.xml
EQUI_CastSpellWnd.small.xml

put these files in my folder with no luck.

Tried renaming EQUI_CastSpellWnd.small.xml to EQUI_CastSpellWnd.xml didnt fix it, but however now it came up with a fault message and loads default.

so... what must i do to make this work? once I make it work I can make it vertical.

do i need to put the .png file in a certain directory? or what should i do with the XML's, or what am i doing wrong?

thank you.
