eM Client Application Error

 I receive this message when I want to use my iCal calendar : eM Client Application Error

I have activated my licens - Can anyone help me out how to fix this.

Thank you. ![]( “Image null”) ![]( “Image null”) ![]( “Image null”)

Hi Tinna,
unfortunately the image links in your post are broken, so I do not know what your problem is.
Can you copy the error for me again?
Could you also copy the content of the Tools>Operations>Log window next time you experience this problem?
