Audio setup problem after trying to install Soundflower

Hi,

i was trying to install Soundflower for record sound from my browser and after reboot of my iMac, i didn't see anymore my audio interface listed in my options (an TC Electronics Impact Twin). I tried to unistall Soundflower and TC Electronics driver but without luck. I've check on TC forum for tried to solve this issue and i found a good tutorial but nothing is change. In the screenshots you can see my setting... Impact Twin audio interface is connected with firewire cable 400-800 and she worked fine until i installed Soundflower... ****!

It's can be a Mac problem?

Any suggestion?

Thank you in advance

All the best,

Rob
