citrix client ps 4.0

I am using, I think, citrix 11.0 on my win 7 machines to connect to my ps 4.0 server farms on W2003 - both published apps and the old style ica client config where you can specify an application to start in the client config.

Anyway, my beloved PN is gone.  Am I supposed to be using citrix receiver now?  And if so, which version is compatible with my old setup.

thanks,
