It gets stuck. Rated 4 out of 5 stars

I love FireFTP and after more than 5 years I have never had any issue with it until I updated it to the last version. When I select many files, more than 10 for example, and drop them to my HDD from the server, it gets stuck after have downloaded 5 or 6. I have to abort and start again. Virtually I can't download folders with many files inside since it gets stuck. Any idea why this is going on? thanks!
