Deleted gmail after synchronization?

After trying eM Cient, all mail since 8 July is gone from gmail in all folders.
All new email is deleted after about 1 minute.
Updated to latest version today and it’s seems to keep the new mail.
Where is my important email? Can I search on computer?

Hi, are you using IMAP with your account?
Can you see your messages online using your webmail (are the “deleted” messages available on the server)?
Do you have any rules setup in eM Client?
What version of eM Client are you currently using?

Thank you,
Paul.
