Can someone please explain to me how I can get reason 3.0 and Cubase Artist 6 to work together in the slave mode?
Here´s the Rewire Help article from PH
https://www.propellerheads.se/substance/rewirehelp/index.cfm?fuseaction=get_article&article=cubase4_0
It´s described w/ Cubase 4 but it´s the same in C6.5.
As Reason 3 is a 32bit application you´ve to run C6.5 in 32 bit mode as well.
Under Mac OSX,right-click on Cubase.app and choose 32bit mode.
I can´t help you w/ Windows here as the PH forum is closed at the moment and none of the info there is retrievable.
Thank you. It’s working! 
You´re welcome
