Well I guess something is beginning to happen. Under 'Transfers' I have a page of files that are in various stages of downloading. But 'Status' shows project backoff and a time counter. Some say pending and others retry. What does all that mean? Based on the file size and my 25 MB download speed I'd have thought it would take very little time.

Good grief! It started to download for about 15 sec then shut off and says pending more than 4 hr. Is this typical? This is going to take days.

This is quite typical yes. The Project back-off function was added to relief project servers from being hit by all those computers out there all the time. As just your computer won't make a dent, but add a couple of thousand computers all asking for work at the same time, and you have a denial of service attack.

Thus the back-off. Albeit that in 6.12 it's a tad too long set. 6.10 and 7.0 (not released yet) have shorter back-off times. At least you can override by clicking Retry Now. Don't abort the download, this will irrecoverably delete the task being downloaded as well.
