Hello, I made a DLL using Matlab's real time workshop. Using Labview 5, it was possible to use this DLL by means of the CIN block. Now I use Labview 6i, the same DLL as before gives an error, resulting in crashing Labview. The exact error reads: "File I/O: LabVIEW.exe - Application Error, The instruction at "0x02e01ec9" referenced memory at "0x00000000". The memory could not be "read"." Please advice.
