[Solved] ReWire configuration/coordination message?

Part of the ReWire spec is that a ReWire client will "announce" its presence to a ReWire host. That's why when you go Insert > ReWire Device in SONAR the list is already populated with candidates. However also note you can't mix 32 and 64 bit apps that use ReWire, it's either one or the other. It looks like something may be trying to bridge the ReWire connection. (For the longest time I couldn't use ReWire with SONAR because P-Heads were slow getting out a 64-bit ReWire DLL.) 
 
I'm not exactly a ReWire expert, although I do use it often to run Reason as another "instrument rack" inside SONAR. However, what I assume the message means is that you have used a ReWire client-compatible application in a stand-alone mode, and something about it changed. It has therefore announced the change to SONAR or to whatever is trying to bridge it.
 
Unfortunately you cannot exclude a ReWire device in the Plug-In Manager the same way you can exclude plug-ins. If you never use ReWire:
 
1. Search for rewire.dll and rewireservice.dll (if present).
2. Rename them to rewire.dlx and rewireservice.dlx
 
This should gray out the ReWire option under Insert, so that may prevent the error message from popping up - please report back and let us know if that's the case.
 
If you decide you want to get into using ReWire, then search on .dlx and change the name back to .dll.
 
Hope this helps.

When you report back, let me know if you're using all 64-bit programs. I'm curious why you're getting a Bridge-related error message. Seems odd. Maybe you have a 32-bit rewire.dll hanging around in your system.
 
FWIW I've fixed several peoples' ReWire problems by instructing them to search on rewire.dll. Sometimes multiple versions will have been installed, some 32-bit from previous installations, some 64-bit. I usually advise renaming all except the most recent one and if that solves their problems, to delete the older ones.

Glad you got it sorted out!
