as soon as I try to do ANYTHING in the online calendar, the whole program (eMClient) stops working. I close it , I restart, same thing. Not possible anymore to work with eM client.
Which version of EMClient are you using and which email account calendar are you using. Eg: Is it a Gmail , Hotmail, other calendar. Has it ever worked before.
Hello, sorry for not answering. I had to completely set up my system. I am not sure where exactly the problem was. The calendar I am using is “fruux”. It always worked before. But I assume the problem was with fruux. Everything seems to be OK now.Thanks for trying to help.
Ok glad its all working now 
Ps Yes sounded like Fruux was the problem.
