Windows 7 Update screwed up my compiler, maybe

I am currently using a MATLAB 2013a to operate my NIDAQ USB 6353, and have been using a Windows 7.1 SDK compiler to run the NIDAQmx.h library. Everything worked fine until I did the critical update on my Windows 7 (64 bit) computer. Now, I can't even create a task on my NIDAQ card. Many signs point towards the compiler because I've seen this error before, and the fix was to go into the NIDAQmx.h file and comment out the datatype of the TaskHandle and change it to uInt32.

/*typedef void* TaskHandle;*/ typedef uInt32 TaskHandle;

Any suggestions would be greatly appreciated!

Please post more details:

1. Which one was the critical update? Do you have the KB number?
2. Did you try to uninstall this update and does it successfully work afterwards?
3. Post a complete copy of the error message.
4. As far as I understand the posted code solved another problem. Please explain why you think that it is relevant here. Converting a void* pointer to a uInt32 is a dangerous method on a 64 bit system. I'd definitely avoid such ugly tricks.
