The software was on the pc for 5 minutes then I realised a new version was released whilst I was on holiday so I downloaded and installed that. I tried to import my opml file but it just tells me that there were some errors on the subscription and then doesn’t subscribe to any of the feeds. No log file can be found so i don’t know why it failed so I can’t troubleshoot and fix it 🙁 Email sent to the developers, who don’t have a support forum, so we’ll see how long they take to respond.
