eM Client will not let me send an email.

I set up my email account, added my addresses, got a free license and activated it, and the eM Client allowed me to receive emails, but when I go to compose and send an email, it says I have no account set up and asks me to do so. It shows a pop3 server, but even though the automatic setup says it found a SMTP sever, it will not let me send an email and does not tell me how to manually set up an outgoing SMTP for my email, which is a Roadrunner address. Any ideas? Thanks

Open Tools - Accounts - New account - Mail and click Next. New window will appear where you can configure the account manually.

If you are using DEMO(free version), and it is expired, then you may have problems.
