Unable to Import "Sandbox with HDP Advanced Security" in VMWare Fusion 6.0.4

Hi
I’m unable to import “Sandbox with HDP Advanced Security” using VMWare Fusion 6.0.4
I receive two errors; the first warns me that “The import failed because …/XASecure3.5.000-on-HDP-2.1Sandbox.ova did not pass OVF specification conformance or virtual hardware compliance checks” and encourages me to Retry (with relaxed validation)
But it still fails, with the error “Capacity mismatch for disk …/XASecure3.5.000-on-HDP-2.1Sandbox-disk1.vmdk”, finally saying that “The operation could not be completed”.
