ExtremeCap U3, RECentral, and El Capitan I recently upgraded to El Capitan and RECentral, the streaming application I use to play my Wii U on my iMac, no longer starts up reliably. Sometimes it just beachballs for 10 minutes until an image is displayed. 

Is there a fix for this?
Looks like they just put up a new firmware for the Extremecap U3. Recentral now launches immediately for me. Also - after I updating the firmware - the beta version stopped working. I went back to version 1.2.15 and all is well.
