PBKDF2 HMAC SHA512

Hi,

I am currently trying to test my password encryption (PBKDF2 HMAC SHA512) and are having an issue trying to crack a simple password.
I can’t seem to get oclHashCat V1. 37 to work. This is the first time I have used this application and not sure if I‘m using it correctly or have correct 

configuration.

Can someone shed some light my way please.

Password:    MyPassword12345
Encrypted password : U****/DAqx****qHgl***7YVY******AM4******BWs=
Salt:                mvO24idgW2UViAUi7Beufg==
Iterations :  5000

The configuration being used is

cudaHashcat64.exe -m 12100 <HASHES FILE> < DICTIONARY FILE>

The Hashes file contains 
sha512:5000:U****/DAqx****qHgl***7YVY******AM4******BWs=:mvO24idgW2UViAUi7Beufg==


Thanks
