Hi there,
Same here.
Had problems with v9.1.2082 which corrupted the Archive database and made program FC at the dreaded startup splash screen Checking Database. (link to post in this forum here)
As asked by @Gary I updated to latest version v9.1.2106 and that seemed to work. Installation and starting up eM Client worked fine.
Only to find I now cannot send any mail anymore: eM FCs when the Send button is pushed, no matter what the content of the mail is (even simple line of text makes it FC).
Although I do use IMAP, I have the client archive locally after few months so I cannot simply remove the database like you suggest, for that would delete most of my mailing history.
Since not being able to send mail anymore I grew quite desperate.
So I searched around on the Internet and found beta versions 9.1.2124 and 9.1.2125. Both gave the same result of not being able so send mail.
This is rather annoying for a program whose sole purpose is to be able to send mail.
Quite annoying indeed.
Regards,
