rewire problems with reason and ableton

I would like to know how to rewire both reason and ableton into cubase 6.5

I rely on these programs to work with cubase to make music and can’t seem to work out how to do it.

I start them up but they don’t show up or even go into rewire mode when cubase is open. I am running it as 32 bit so shouldn’t be a problem.

I am using ableton 8.3

and reason 5

Both worked with cubase 5

There is no display in the device menu like there used to be in cubase 5.

This is driving me a bit crazy!

Please can you help me…
