Well FUCK YOU then.
LDB, there shouldn't be a problem with Sonar, I don't think it's the version. The article I wrote was for Sonar 4 and it worked fine although I initially had many problems to get it to work, that's why I did the article. I would suggest setting up the inputs/outputs first, then start to Rewire one program into another. If that doesn't work, maybe you should ask on the Cakewalk or Propellerheads site and see what they recommend!
