Element 3D Missing Texture

Check the default texture paths in the E3D editor settings. Otherwise it's impossible to say much beyond the fact that your file paths appear excessively long and in fact may already be truncated in the OBJ files. Verifying any of that would require more info on what file you're actually trying to import from where, how it was created in teh first place and so on.

I also tried re-installing it but it was the same problem.
