Error ArgumentOutOfRangeException:

When I start the client, the following error occurs:

System.ArgumentOutOfRangeException: Los pasos (ticks) deben estar entre DateTime.MinValue.Ticks y DateTime.MaxValue.Ticks.

Any idea of how to fix it?

Is this error preventing you from opening eM Client?

Hi Gary, thanks for responding. It opens but then immediately closes. 

If your accounts in eM Client are all synced accounts, like IMAP or Exchange for email, and an online calendar and contacts, you could delete your database and start again.

To delete the database, close eM Client, and then delete or rename C:\Users_username_\AppData\Roaming\eM Client. You may have to show hidden items in Explorer to do that.

When you restart eM Client, you will have an empty database, and you will need to setup your accounts again. Once that is done your data will re-sync.

Thanks so much, I will try this and report back.
