HELP! Trying...

open up the old qst in zquest and file>>export to export the tiles. then open up your new quest and go file>>import, and look for whatever you named the exported tileset. the colors might be a little bit off, but youll just have to recolor them. or if youre just trying to import a few tiles, not the wholoe set, open up your tiles page, rightclick on an empty tile, and click grab.. then look for the tileset you exported earlier and choose whichever ones you want.

Thanks!
