I have faced same problem .

My after effects template folder structure was like this

E:\05Logo演绎AE合集\Logos\projects\diamond.aet

it says doesnt exist. then i copied the aet file to another drive like this F:\diamond.aet . i opened and it worked.

Their might be some problem with path where after effects may not recognise another languages or special characters like i was having.
