No In-call after upgrading freepbx 2.11

Hello,

I just upgrade freepbx to 2.11 version, and I loose all incoming call.
I only could make outside call.
All my trunks looks ok.
I only get a problem in this module
System Admin 2.11.0.7 Schmoozecom.com Disabled; Pending upgrade to 2.11.0.35

Is it important to get this module OK?

I use Sip from OVH.
