I’m sorry… this may be a really, really stupid question.
But on this site: http://www.emclient.com/em-client-wit…
It tells me: Be aware in order to use your calendar account you have to access it using web interface first.
How do I do that?? I just don’t understand… its probably very simple, but I really want my calendar to sync up! I just can’t seem to get rid of sync errors.
Help? and Thank you!
Hello,
open your web browser, enter the following address: calendar.google.com, enter your Google Account email and password, and click Sign in. That’s it!
oh. Well, that is sort of what I thought. it didn’t work. I’m still getting the following error: Synchronizing calendar '[email protected]/My Calendar/" failed with an error: Specified cast is not valid.
Have you any ideas on that error?
thank you for the reply!

Hello,
please download and install the latest version of eM Client http://www.emclient.com/dist/v4.0.149… and let me know if it helps.
Unfortunately that did not help. I tried deleting the account and re-adding it as well. 
Yay! I got it working.
I had recently started over with my OS and then tried using this email client. since my last reply to this thread, I realized I didn’t have any service packs installed for Windows. I got it up to date and the calendar is syncing beautifully. Thanks for the replies! Maybe this will help someone else.
