Won't Open or Send Messages

Frustrated! I am having trouble even getting eM Client to open. It also keeps having problems sending email. The error message says to keep checking my settings. I have triple checked the setting both on eM Client and on my gmail account. If this continues, I will have to delete the eM Client software and try something else.

please post here a screenshot along with the text from the tab Logs in the Operations window. Thank you.
