Hashcat Bruteforce attack

[lucask]

I want to launch a bruteforce attack against this hash (yes, a standard bruteforce attack, not a dictionary attack). I know the string ends with '66'. So I denifed a rule called myrule.rule which contains '66$' and probably consists of all ascii characters.

What I tried to do so far is:

Code:

cudaHashcat-plus64.exe -a 3 -m 0 hash\myhash.hash -r rules\myrule.rule

But it doesn't execute:

Code:

\oclHashcat-plus-0.08\cudaHashcat-plus64.exe [options]... hash|hashfile|hccapfile [dictionary|mask|directory]...

So I'm probably failing somewhere on syntax. Also I tried to read the examples, but I don't really understand them. How do I go about to launch a bruteforce attack for an MD5 hash who's unhashed string certainly ends with 66 and only contains ascii characters?

Thanks!
