C&C 3 world builder not working when importing Height Maps. Why?

[Flamm1ng_Dem0n]

So....I am trying to import custom height maps into the C&C 3 world builder....but it is not working for me at all. I also (NOT MATTER WHAT) say "Wrong File Size". Not only that but its getting REALLY annoying and frustrating. I have even tried to save it through Photoshop CS3 and not even that works. And yes.....I have saved it as a 16-bit Raw file...but it still does not work. So my question is: Am i the only one having this issue with importing custom Height maps into C&C 3 world builder or are others also having this issue? And how do i fix this issue? And yes i have tried to import .tga files into C&C 3 world builder......but it does not even make a proper imprint into the map. So that's out of the question. So.....is the "Import Height map" feature disabled to the general public and only available to the makers of C&C 3? And when a person who is not a developer tries to access this feature it always gives this error...is that what's going on?

Thanks for any help given
