[MT-AU Public] CAPsMAN on 6.38.7 not working after update

Hi guys, I just upgraded an RB2011 we are using as a CAPsMAN router and the CAPs aren't coming back online. Everything was working OK previously but we just did the bugfix update to keep up to date, but now the CAPs aren't coming back. I have tried disabling and enabling everything on the CAPs and the CAPsMAN router but it's not seeing any radios. Any thoughts ? Regards Paul
