I create a Monogame Content Project to convert assets into XNB. For FBX file without texture there is no problem: the file is correctly converted and when I load XNB into my project everything is ok. The problem occours when i have associated to fbx file a texture map: in this case both FBX and PNG files are converted to XNB but when i try to load these XNB files into my project the following problem occours:

"ContentLoadException: Could not load Models/maze1 asset as a non-content file!" Note: maze1 is the XNB file that was converted from FBX.

How can I solve this problem? Thank you in advance
