I don't use an .NFO file myself so you could try adding that as a seperate file in your upload as it could be the issue...? (make a folder and put your upload and NFO file into that then upload it)
Also you only need the ttnumber for iMBD to work here (see below)

Try doing the above suggestions and see if it helps;)
Good luck
