it was so crazy when i tried to import my 3 textures ( which i edited in photoshop into tga*) into the maps, this same error occurs nearly every time, then the program shut down by itself,,, i didn't even get a chance to save my work, so i lost my whole work up to that time. another thing was the program always occurs unpredictable trouble and mistake, then its not allowed us to undo anymore. which is @$%^&. = =!. so i have to redo it again and again..

i just wanna say, this thing maybe easy for the local students or who is good at doing the software.. but for me, without any basic knowledge..it was so difficult to complete. and i was trying to figure it out for several nights, but still....

hope things will change after i get use to it..
