Last week, I downloaded feedHopper for the iPad and was able to import an OPML file. All my folders with feeds were successfully loaded into feedHopper and I was able to read articles as usual. This morning, with one exception, all my folders only have one feed in them. For example, I have a folder called News & Politics and it is supposed to have 8 feeds in it. This morning there is only 1. I tried to re-load the OPML file but it said that the file was a duplicate and nothing happened. I tried turning the device off and on, which didn't help. Any other ideas?
