Thread Subject: DAQ PCI 6229 help needed

I hope I can find here some for our problem. My research group is
having trouble by new DAQ card to work with Matlab.
We use a National Instrument PCI 6229 Card and the latest driver of
nidaqmx.
But we already get the same failure messages if we try to register
the nidaqmx.dll

>> daqregister('nidaqmx')

ans =

'nidaqmx.dll' not found. Make sure it is on the MATLAB path.

>> daqregister('D:\Matlab\toolbox\daq\daq\private\mwnidaqmx.dll')

ans =

'nidaqmx.dll' not found. Make sure it is on the MATLAB path.

Also if we run daqhwinfo we receive a failure message.
>> daqhwinfo('nidaq')
Caught unexpected exception of unknown type.
Unexpected error status flag encountered. Resetting to proper state.

And if we try to receive a signal its even worse.....

>> aimx=analoginput('nidaq','dev1')
??? Error using ==> analoginput.analoginput
Error using ==>
analoginput.analoginput>localCreateAnalogInputObject
An unexpected error occurred.

I or better we hope here are some people who can help us.
Because we need to run these card immediately.
