Windows Mobile Standard

I had a Sirius program, that ran great for a while, but now for some reason, I always error out when connecting. It seems to be a bit of an old program. I have other friends with WM6 and they are having the same issues. Anyone konw where I can get a current version of this software, or know somewhere I can go to stream my Sirius on my T-Mobile Shadow? Windows Mobile 6. Thanks!
