Hi
You need to ask them to save in Cadence Ascii format since Altium can only import the binary version if you also have Cadence installed (which means you could open the original anyway...).
There is such a file on the forum somewhere for the 1050EVB as a starting point since it uses the same footprint.
Regards
Mark
