It is probably an error in the custom step. Implementing the custom step in VC++ can be very tricky. Even the smallest mistake entering the info can cause problems.
To alleviate that, I created a LabVIEW VI to implement the custom step outside VC++. you can download the VI from here:

It is the one named
CIN Custom Step.
Let me know if it was of help.
