What steps will reproduce the problem?
1. Issue the command: 
./truecrack -t /home/asdf/Desktop/crypt -c string -m 21 -b 1024

What is the expected output? What do you see instead?
Immediately after I issue the command I see the following output:

Not Found password for volume "/home/asdf/Desktop/crypt"
Try "-1025" words.

What version of the product are you using? On what operating system?
Downloaded the version from here 'uploaded Apr 3, 2012'; OS Fedora

I experience similar problems

I have 2 "types" of truecrack - GPU and CPU executable.
My Test file is called tim_2467 (It has the passcode of 2467)
Output from both runs is
tim@Ham:~/truecrack-read-only$ ./truecrack -t tim_2466 -w test.txt -v
0 password : 123
1 password : 2466
2 password : 321
3 result : 71
0 result : 0: NOT DEFINED
3 result : 71
1 result : 0: NOT DEFINED
3 result : 71
2 result : 0: NOT DEFINED
Not Found password for volume "tim_2466"
Try "2" words.
tim@Ham:~/truecrack-read-only$ ./truecrack-CPU -t tim_2466 -w test.txt -v
0 password : 123
1 password : 2466
2 password : 321
0 result : NO MATCH
1 result : MATCH
2 result : NOT DEFINED
Found password for volume "tim_2466" in words file "test.txt"
Password[4]: 2466

Password file has the following in it....

123
2466
321

Whilst the GPU model is very fast it does not appear to work !! 

When I compile the GPU Code I get some warnings.... but the Code compiles and 
executes seemingly without throwing any exceptions.

Any suggestions anyone ?

The software was built and tested for Cuda framework version 4.0. I think you 
have the latest version. I tried with the new version of Cuda and I tested a 
lots of problems and your specific error.
For this purpose, I am developing the new version to support the new cuda 
version and nvidia boards (until GTX serie 6). I think to public the new 
release at the end of this month.

There are some strange issues with truecrack and CUDA4.2.9 (latest package on 
arch linux)
i have created a wordlist with crunch that contains all combinations for 
lowercase alphabeth with 6 letters

when i run truecrack-GPU its much slower than truecrack-CPU in KDE konsole but 
it does noth say NOT DEFINED

but if i try to run it on bash, truecrack-GPU tells me NOT DEFINED on every 
line from that file

I can reproduce the issue, if I set -m 13 the program runs fine, but everything 
greater than 13 produce the error "Try "-1025" words"

This is without the GPU code at Debian Testing

I suggest to try with the TrueCrack version 2.0

"NOT DEFINED" is the message when the gpu doesn't launch correctly the cuda 
kernel function. TrueCrack can saturate the gpu board and the system doesn't 
allow this type of consumption. Try to turnoff the xorg graphic server, and 
disable the framebuffer. A easy solution is to unplug the monitor cable and 
make a remote access to the machine with ssh. (I suggest to try the latest 
testing version)
