oclHashcat64 syntax

Hey everyone. I'm brand new here and very new to using oclhascat. Currently running it in windows 7 and I keep getting this error message

Usage : cudaHashcat64 [options]... hash|hashfile|hccapfile [dictionary|mask|directory]...

Try --help for more help.

After giving the following command:

cudaHashcat64 -m 0 -a 1 \e::\Assn3hash.txt\ \e:\Cracking\Passlists\Passwords.txt\

Assn3hash.txt is a file with an md5 hash value in it and Passwords.txt is a file with a few combined passlists. Where am i going wrong in my code?

Thanks
