Free downloading too slow for very large files like hd-mesh

After about 30 hours of downloading (currently in process) hd-mesh-v4-complete on free download, I only have 27.1 mbyte done out of 118. At this speed it will take another 5 days to complete. I just registered on PRO and I would like to know if there is a way I can move on to PRO speed right away although the process was started on 2 mbits/s. A very quick response would be highly appreciated. Thank you.
