FWIW, if you sign up for a 7-day trial of Internet streaming on the SiriusXM site, it works. I notice that with the trial, you get the Sirius channel lineup, but if the Internet streaming is tied to your XM account, you get the XM lineup which doesn't work. As a longer term solution, if you sign up for a streaming account that is not tied to a radio but still tied to your account, it also works because it gives you the Sirius lineup. It's $8.99 versus $2.99, but you get all the premium channels and at least it works with Pulsar. When the gurus here at Rogue Amoeba figure it out, you can switch back to your XM-tied account.
