Blender to FBX?!

You see, I have a daunting error in my unity after importing a model ftom Blender to it! The error is, that “Blender could not convert the .blend file to FBX file”.
What on earth do I do?
Thanks

Try switching to “Object Mode” and then save your model. For some reason if you save in Edit mode Unity has trouble converting to FBX. Not sure if this happens every time. But open your model in Blender, switch to Object Mode and save… then give it a try reimporting into Unity.
