Models show up with white texture

[TheWhiteWolf]

Hey, I have encountered a serious problem. When I import a model with some texture, it shows up with white texture. I open the model in Magos' and it's fine. Then I check the texture path, and it is okay.
What could be the problem?
+Rep for help

Click this if its a tree.

If its not, my guess is that the model or texture is corrupted.
