Is there a C version that does what the MAX 1-D Interactive does?

Question

Is there a C version that does what the MAX 1-D Interactive does?  Or a solution to the problem below.
I got the MAX 1-D Interactive to work with my stepper motor.  The hardware setup is at the bottom.
I am trying to write a C program in Visual Studio 2010 to control a stepper motor. I found an example program called 1D Straight Line Move.c in
C:\Program Files\National Instruments\NI-Motion\Documentation\Examples\NI-Motion Help\C
I copied the example file and the needed .h, .c and .lib files into a Visual Studio project.  I changed the velocity, acceleration, and deceleration to match the values in the MAX 1-D Interactive.  The solution builds, but when I run it I get the following error message
Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call.  This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.
Setup:
I am running the latest NI Motion Software.
PXI-7334 connected to UMI-7774 using I/O Motion cable
UMI-7774 connected to P70360 Stepper Driver using control cable
P70360 Stepper Driver connected to NEMA 23 (T21NRLC) using Orange (A-), Black (A), Yellow (B-), Red (B)
NEMA 23 is powered by 120V AC power supply
P70360 Stepper Driver is set using DIP Switches (I tried to use the P7000 software tool that came with it, but it never found the driver):

No I am not using Visual C++ MFC.  I am using an empty C++ project in Microsoft Visual Studio 2010. Although I eventually want to create a .exe file from this project so I'll have change project type.
The motor runs using MAX to control it. 
It did run using the 1D Straight Line Move.c project, but it gave me the below errors.  That night I unplugged it because the stepper motor gets hot.  The next day MAX still moves the motor but the 1D Straight Line Move.c project doesn’t and I still get the errors below.
I am getting two errors:  (I was getting the same errors yesterday)
Run-Time Check Failure #2 - Stack around the variable 'errorCode' was corrupted.
Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.
I think the errors come from using the functions in flexmotn.h.  The functions look like they are being used correctly, but I can't find where they are defined.  They are probably defined in FlexMS32.lib.
I attached the files I am using.
I haven’t tried any of the other examples.  1D Straight Line Move.c looks like the simplest and closest to what I want to do.
