Trouble with maskprocessor piping

Hello! First time on here so be gentle! I am trying to test my understanding of hashcat by trying all combinations of Lalphanumeric strings of length 10, where there can only be at least 8 of the same letter/number in the total hash and at least 2 consecutive letters/numbers for a SHA256 hash. I created a mask file, which I named mask_file.hcmask. In it contains the following - 

Quote:?1?1?1?1?1?1?1?1?1?1

This is for the constraint I'd like which is length of 10.
I stored my hash in a file called hashin.txt and then tried this following command in my command line (Windows) -

Quote:mp64.exe -r 8 -q 2 -1 ?l?d mask_file.hcmask | cudaHashcat64.exe -m 1400 -a 3 -o hashout.txt hashin.txt

This was the output - 

Quote:C:\Users\[MY NAME]\Desktop\cudaHashcat-2.01>mp64.exe -r 8 -q 2 -1 ?l?d mask_file.hcma
sk | cudaHashcat64.exe -m 1400 -a 3 -o hashout.txt hashin.txt

[s]tatus [p]ause [r]esume [b]ypass [q]uit =>

It just "freezes" at the end. I let it go for about 10 minutes and no updates were given. I was also not able to hit "S" for the status, so I just exited out of my command line. Another thing I noticed was that it said the mask I was using was too small so I added 5 "?1"s to my mask file (to test strings of length 15), and it did the same thing. Any help would be greatly appreciated. Thank you!
