Uploaded files sit in Queue, but don't update page

I've uploaded files and they are sitting in the queue not updating the website. The "date modified" for the existing files are still the old date, and the new ones in the queue, while appearing to "cycle" don't update the website or change the "date modified". They just continue to sit in the queue. After about 10 minutes of letting it repeat its "cycle" of trying to update, I get an error message from Microsoft saying that there is an error with SmartFTP and that it will shut down.

Can someone help?

Thanks.

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

Then post the log from the transfer queue. Double click the file in the transfer queue to get the log.
