Problem with PNG in RPGMXP

 
My problem is that when i try to import a tileset, to be more speciffic , the world map
made by inquisitor or something like that, the program shows me an "critical error ..."

the problem is with the png? with my pc? with my rpgmaker xp?
maybe the PNG is to big?
the attributes are 256 x 16448 x 24

help me please! 


i have Rpg maker Xp 1.01 - Postality knights edition v2.0

Its with your pc
Hmm you have Vista ??

nope.. i have w98 SE
the fact is that when i convert the PNG to JPG, it doesn't make any troubles when i import it, but, it doesn't give me the chance to select the traslucent and transparent color.. so i can't make the map very well..
that's why i think the problem is with the pc..i'll install another version of rpgmxp but i doubt it'll work..

I think it's the size.  I got something like that when I tried to import a really big tileset.I had no problems with a 150000 pixel tileset, but it does make sense that the cutoff would be around 160000
