Invalid sequence value error

I keep getting an error message when I open eM Client that reads, “An error occured Uploading item(s) to folder ‘My email address’ failed with an error: Invalid sequence value.” How do I fix this error?

Enable GData logging for the problematic account in Tools - Settings - Advanced and wait until the error message appears. Then send us the logs and we will advise you further.

Here is the log after I took out my email address:

Hi,
I am sorry but this log is not the log I asked you for. Go to the menu Tools - Settings - Advanced, enable GData logging for the problematic account and wait until the error message appears. Then send us the logs using the same logging settings window. Thank you.

It produced two logs. I will post one below. Let me know if you also need to see the other.

Can I email these logs to you, as there is a lot of personal information, email addresses and phone numbers within the log itself?

Of course you can send it to me - send it at wilson@emclient.com please.

The solution you emailed to me which said “It seems that there is a conflict caused by importing new events. You can workaround it as follows: Right click on the calendar folder and use the “Repair” button in its properties. Then let me know if it helped.” fixed the problem. Thank you for your help!! Denis
