Thanks for the advice, I found that the waves effect wasn't in the right folder so I moved it. Now when I start up sonar, I see the waves GTR3.5 scanning all of it's components, but at a certain point it stops and I see a window that says 'select waves 9.3 plugins folder'. When I try to find it, it won't let me go any further, and if I press cancel, the effect still isn't in the list.
