Microphone not working in version 2.0.7

I have a microphone connected via a Hercules DJConsole RMX2 and it has been working fine in djay Pro 2 up to version 2.0.6. Now that I have installed 2.0.7 there is no signal on the microphone meter and nothing is recorded from the microphone. If I use djay Pro 1 or another app such as GarageBand the microphone works fine so I am confident there is nothing wrong the microphone, the Mac or the Hercules, it is a problem specific to version 2.0.7 of djay Pro 2.
Any help gratefully received,
