Hashcat APPCRASH

I have been running this command virtually all day -
C:\Users\Dad\Desktop\oclHashcat-2.01>oclHashcat64.exe --session md5 --show -o found.txt --outfile-format 2 "C:\Users\Dad\AppData\Local\Temp\tmp7C41.tmp"

until now - Hashcat keeps crashing

At first I thought it was because of the size of the file 561,000 hashes so I reduced the amount 319 as in the tmp file above.  oclHashcat runs fine using the Hashcat Gui and is running the 561,000 hashes now but I cannot access the pot file with the --show command without it crashing on the command line.

Any ideas/help?
