Simple Question - Extreme Beginner

Good Afternoon,

I have been reading / attempting a simple command in cudahashcat64. My interest in hashcat is because i have a USB flash drive that was hidden by TrueCrypt a year ago, and of course i no longer remember the password to mount the drive and see whats on it, if anything. So, I decided to start with the basics, learn, and hopefully one day be able to retrieve my password from the annoying truecrypt volume. Sadly, i guess even the basics of the basics are beyond me atm.

What i am trying to do is take the example that was provided with the download, and just get it to output it into a file called crack.txt that is a text file within the folder. It completes everything fine but does not report it to the .txt file. Please advise

My command line:

"cudahashcat64.exe -m 400 example400.hash example.dict -o crack.txt
pause"

Its basically the example code just with the output value. To me it seems pretty simple but its not delivered to the crack.txt file. Is there something wrong with the syntax or am i a nub who should just give up.

Thanks,
