Problem communicating with NI-DAQ 6353 using NI DAQ MX DLL's in MATLAB

I'm currently using the NI-DAQmx Device Driver 9.7, and am having trouble loading all of the functions available in the DLL (see below). However, no error gets thrown when I create a task, but when I try to create an Analog output voltage line, it gave me the following error:
Warning: NIDAQ_Driver Error!! -- 01-Mar-2013 11:59:01
-200088::Task specified is invalid or does not exist.

In NIDAQ_Driver>NIDAQ_Driver.WriteAnalogOutLine at 197
In NIDAQ_Driver>NIDAQ_Driver.WriteAnalogOutAllLines at 218
However, when I called the NI IT service guy, he helped me communicate with the DAQ using the Matlab control toolbox (followed directions from here: http://home.hit.no/~hansha/documents/matlab/training/Data%20Acquisition%20in%20MATLAB/Data%20Acquisition%20in%20MATLAB.pdf)
So in summary, if I use the MATLAB control toolbox, I can communicate with the DAQ. But if I use the DLLs, I can't even create an analog out task. I really need to use the DLLs because I have a lot of control code already written in MATLAB. This has worked before, but it seemed to stop working after I updated the drivers. Also on the other computers in the lab, this code seems to work fine on the NI-DAQ 6351 (using R2010B, Driver 9.2)
Thanks,
Ed

Actually, I found the fix with the help of a post-doc in my lab:
We had to edit the nidaqmx.h file to change the pointer type for the TaskHandle from *void to uint32.
