oclHashcat cannot crack NT/LM hash?

I have used Cain and Abel to extract the system's LM/NTLM hashes. 

LM Hash: AAD3B435B51404EEAAD3B435B51404EE
NT Hash: 63BF854993F377F7F911343DD3864341

The real password is "@a1234567" (without double quotes)

I used mode 1000 and -a 3 to crack it. It exhausted cracking... Anyone knows why?
