How can I get past an error when importing the Data Mirgration Framework model?

I get an error on the AOS when trying to install the DataMirgrationFramework.axmodel file using the power shell.  This is Beta version 2.0 on AX2012 FP CU3.

The error is "one or more conflicting model elements already exists in an installed model".  There is nothing other than this to go on so how do I get past this and finish the DMF installation?

Thanks,

Eric
