unable to begin iphone hash on Windows 10

[coprophile]

I'm new to this so please bear with me. I made the text file testHash.txt with my hash. It looks exactly like the example hash for iTunes backup >= iOS 10 ($itunes_backup$*10*...). I put that into my hashcat-5.1.0 folder along with the wordlist milw0rm-dictionary. So in command prompt, when I have...

C:\hashcat-5.1.0>hashcat64.exe -m 14800 -a 0 hashTest.txt milw0rm-dictionary.txt

I get

Hash 'hashTest.txt': Separator unmatched
No hashes loaded.

you must make sure that the file named "hashTest.txt" exists.

hashcat can't find the file "hashTest.txt" within the directory
