AAE error -20038 Rewire HELP

[HughHM]

I am confused about Rewire. I have not yet really understood why it is necessary or what it does, (another "black box" for me) but it has worked.

I am trying to use WavesTune which needs it. What I read and did before is put Rewire on a separate audio track with no output. Then I used WavesTune on the appropriate track.

Now I am getting "the plug in could not be made active because a AAE error was encountered. AAE error -20038"

How do I reload Rewire? Where is it? How did get corrupted?

Help.....
