Timeouts are normal and the transfer is automatically resumed. Please post the complete log showing the resume attempt.

When it resumes it starts all over at the beginning...

Install the latest version from:
https://www.smartftp.com/download


Then post the complete log.

Only times I have experienced failed resumes is when I don't have the append/resume permission on the ftp server.

Can this be the case?

jalmz: Please post the complete log from the transfer queue item.
