if you have not solved I give the solution page 4 of the post

That doesn't make a lot of sense to me..?

http://www.navitotal.com/showthread.php?12066-Color-POI-Icon-pack-error&p=102866#post102866

But what it means?

to make short
in the pack you go in ui-igo9/icons
you have a file named pictures.icon
you have to replace "poi_XXXX.spr " by "$poi_XXX.spr" just as you can see in multipoi.icon

or simplest you just delete this file in archive winrar so you have no problém with decompressed/recompressed the archive
Is it clearer ?

and no more error "failed to open poi_mapclose.spr"
