Driver Crash Problem

I am running Windows XP and I am using Jungo WinDriver to access the Altera PCIe card. Whenever I try to run my software, I get a DLL not found error.

Tracing through the software, I found the problem to be when it tries to initialize the card at software startup.

I used Jungo's Driver Wizard to create altera_lib.c

DWORD ALTERA_CountCards (DWORD dwVendorID, DWORD dwDeviceID)

{

WD_VERSION ver;

WD_PCI_SCAN_CARDS pciScan;

HANDLE hWD = INVALID_HANDLE_VALUE;

DWORD dwStatus;

WD_LICENSE lic;

ALTERA_ErrorString[0] = '\0';

hWD = WD_Open(); <--crash at this line

// check if handle valid & version OK

if (hWD==INVALID_HANDLE_VALUE)

{

sprintf( ALTERA_ErrorString, "Failed opening " WD_PROD_NAME " device\n");

return 0;

}

else

{

BZERO(lic);

strcpy(lic.cLicense,ALTERA_DEFAULT_LICENSE_STRING);

dwStatus = WD_License(hWD,&lic);

if (WD_STATUS_SUCCESS !=dwStatus) {

sprintf(ALTERA_ErrorString,"Could not register license\n");

return 0;

}

}

I took the function above and commented out the entire body and progressively enabled each line until I got to the line indicated above. This calls into windrv.h and the entire program crashs.

The card itself is working. I have some code in MATLAB that test writes to a register and that is working properly.

What is causing the crash and how do I resolve it?
