13. How do I resume my downloads?
In order to resume an uncompleted download, choose the file from the file list and click on the "Resume" button. Alternatively, you may simply double-click on a file. If the download does not continue, please see question 6: "Why can't I accelerate or resume some of my downloads?"

6. Why can't I accelerate or resume some of my downloads?
The Acceleration and Resume features are enabled only downloading a file from a server that supports resume. Most servers on the Internet support resumeable downloads, but some may not.
Another possible reason is the use of a proxy server, this may also influence the resume functionality. If you are using a proxy and do not have Resume functionality, please consult our support team (link to email).
