Windows 7; 600 GB free HD space; 4 GB RAM; Dropbox Plus (paid one year), currently using <30 GB.
I have tried repeatedly to upload an MP4 Audio file (a video recorded on my camera). It tells me it will take about 40 minutes (it's 942,000 KB, and my available upload speed is only 1 mbps), but it fails every time, and Dropbox simply suggests trying again. My account says I can transfer files up to 100 GB, so why am I having this problem? I am not losing my internet connection, and my computer is not particularly busy with anything else.
