"Failure to write HandleOnFBZ_NewFan.cr2 Error #ID=3" There is no such file named "HandleOnFBZ_NewFan.cr2" included in the package, so that's a really strange error. The other is a MAT pose file for making the handle invisible. It's not really necessary, just a convenience so you wouldn't have to go into the materials editor and do it yourself. If you would like, I can IM you with a new download link, and you can try it again with a fresh file.
