X1 can't see Rewire device--SOLVED

I am running Sonar X1 and Reason 6.5.  I want to Rewire Reason using Sonar as host.  When I look at my insert menu, The "Rewire devices" option is greyed out.  How can I help Sonar find Reason?
 
I did this successfully years ago (pre-X1), but I have not used a rewire setup in years.  When I had it working before, it worked beautifully.  Any ideas?
 
Thanks....
SOLVED!
 
I needed to upgrade to X1d.
