Please Help Asap!!!!

I have created a custom skin for the Tauren Chieftain for my RPG by using WinMPQ to extract it, Wc3 Image Extractor to convert it to a .jpg file and Paint Shop Pro to edit it. After this I converted it to a .blp file.
Then I left the project planning to not continue it as it took up too much time and effort.
After TFT came out, I decided to continue with the campaign and I have tried to use the new Import Manager to insert it into my map (as its much easier than WinMPQ).
After inserting it using the path 'Textures\HeroTaurenChieftain.blp' as it is in War3.mpq, I returned to the editor and inserted a Tauren Chieftain. It had the origional skin. I then saved my map and placed another one but it was still the same.

I have attached the skin because I thought that maybe the colours were incompatible or something.

PLEASE HELP AS THE SKIN WILL MAKE THE RPG ALOT BETTER

consider save the map, close it and then reopen it or just use the good old WinMPQ way :P
