Hi

This is the second time this has happened and I am wondering what is going on.
I run windows 7.
I checked the boinc status and noticed all task finished and a bunch of tasks downloading but not getting any data. The errors are like this:
2016-05-19 08:12:10 World Community Grid Temporarily failed download of zika_05_v01.png: HTTP error
2016-05-19 08:12:10 World Community Grid Backing off 1 min 0 sec on download of zika_05_v01.png
2016-05-19 08:12:11 Internet access OK - project servers may be temporarily down.

I deleted all the pending downloads of .png files - I have no idea why I did this - and then all the projects downloaded and started running.

So, no work done from the time it got stuck on these .png files until I noticed the problem and deleted them.

I run a standard setup, nothing unusual, have for years.

Any ideas?
