I can confirm the problem with standard reinstallation of latest Uddeim and CB 2.0, impossible to send a quick message using CB 2.0 mypms configured on Uddeim
Switching to the latest dev version of Uddeim solves the problem but gives another one which is :
Warning: require_once(/Applications/MAMP/htdocs/test.com/components/com_uddeim/uddeimlib.php): failed to open stream: No such file or directory in /Applications/MAMP/htdocs/test.com/components/com_comprofiler/plugin/user/plug_pms_mypmspro/pms.mypmspro.php on line 1230
Have reported on uddeim special forum to Slabbi
