Few things to try:
1. close Flash CS6 and reopen it again and check if you can see Adobe Exchange under extensions
2. Check you have the latest version of Exchange panel (0.9.3). You can get it from here: https://www.adobeexchange.com/
What version of Flash are you running? Can you please get me the version number?
Can you also check the version of Adobe Extension Manager installed in your machine.
My version of Adobe Exchange Manager is 0.9.3 and I'm running Flash version 12. I tried reopening it but it won't start
Im having the same issue... cant find info ANYWHERE!!!
We are currently working on this issue and will get back to you shortly with a response.
