    Can you find the Subcircuit file?

    If you can find it is it where Pspice can find it?

    If it is where it needs to be and you have it included, then are you certain it is a working model that has not been modified since the last time you know it was working? The Analog Devices Models are all good as far as I have tried them.
    Make certain you have the right symbol associated.

    Do you have any other Op Amp models you could try using for your design stage until you get a solution?
