Connection trouble using Matlab

[yetzbacher]

I am having difficulty creating a device object using Matlab for a Picoscope 5444D. I have tried to run the following example code:
ps5000aDeviceObj = icdevice('picotech_ps5000a_generic', '');

The error I receive is below:
An error occurred while executing the driver create code.
Unable to resolve the name PicoConstants.AWG_DAC_FREQUENCY_200MHZ.
If the error is not an instrument error, use MIDEDIT to inspect the driver.

Any help would be appreciated
