Incompatibility between SIMGALLERY & Jtchat entreprise

WIth the last versions of SIMGALLERY i have an issue between SIMGALLERY & Jtchat Entreprise. When System - SimGallery is activated, Jtchat Entreprise don't work (plugin breaking the Joomla json format..). ( http://storejextensi[...]enterprise.html )
I can pay for a VIP SUPPORT to fix this bug and the other from the forum page :

Many thanks
Best Regards
