gmail and eM Client Calender

Just recently, when I try to add a new date event to eM Client Calender (which intern should sync and update my gmail calender), the new date event appears in the calender, but is removed/ dissapears straight away. The only way I can now add a date event is direcly via gmail calender. Up am updating eM Client on a regular basis and running the current version. Can anyone help?
Thanks Roger Hooton

Hi Roger,
sorry for the late reply, is there any error when you try to save events through eM Client? What version of eM Client are you currently running (please find the exact version number in Help>About)?
