problem with .vismat files

hello...so i got some vray vismat and when i wanna "preview" them in the material editor i alway get the alert "dte_wrapper.dll" is missing..and my material turns black...
then i checked the folder but this file exists...its not gone...
did someone ever heard of this problem?...i googled it and someone put this uploaded this file but this doesnt really help^^...
can someone help me^^?

thanks so far..shizzoo

what version of sketchup do you have and or vray version

i use SU 8 pro and vray version 1.48.91...i already deinstalled both programm and re-installed but nothing helped =/..

what particular materials .. mind to share, we will look into it. so far dont encounter such error to any of my vismat materials. i use also su 8 pro and vray 1.48.91

i got these 7gb vismat folder...and everything like wooden floors,walls,bricks...do you want a screenshot?...

is it possible that i installed vray into the wrong folder?...i mean i installed it into the google sketchup 8 folder...

there 2 pics...

ok seems like the error is gone...i can add the vismats..but they appear in black...and not in their real color =/

I have the same problem! Do anyone have a solution?

sir shizzo i have the same problem just reload the jpeg material in the diffuse map.
