Noob question on command line cudahashcat64

[mblanke]

I'm trying to define a command line to crack the NTML hashes of Windows7
I've created a few to test my "script" They are relatively easy and should take seconds to crack, with no results.

cudaHashcat64.exe -t 32 -m 1000 -a 3 ntlm.hash ?a?a?a?a?a?a?a -i --increment-min=7 --increment-max=7 -o=hashresults.txt
pause

When I created the test hashes I went to "http://www.tobtu.com/lmntlm.php" set them up with upper & lower case along with numbers. I will however need the script to look at special characters as well in the future, hence the ?a. Also future consideration the min password length will be 8 char.

This is part of the status output.
