Separator Unmatched! Please help!

[JHACK14]

I am using The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) linux to get itunes-backup password ios 10.
I type:

hashcat -a 3 -m 14800 -d1 --force myhashfile.txt
 
But the error comes and says ($itunes_backup$*10*X7XX5XX2b3aXXbX73XXcc8f0XX4fXX63*X7XX5XX2b3aXXbX73XXcc8f0XX4fXX63): Separator unmatched.

Please help me if you know why!
Is this due to my graphics card? 
Please give a detailed explanation.
