Since upgrading FeedReader from 3.12 to 3.13 a couple of weeks ago all new smartfeeds I have created since the upgade have disappeared whenever I close FeedReader (i.e. whenever I reboot my computer). This affects only the new smartfeeds created under 3.13. All smartfeeds created under 3.12 are completely unaffected and remain fully functional.
The download file used for the upgrade was the .zip version and it is installed as a portable program on a USB HDD. The computer runs under Windows Vista Home Premium (32-bit) with SP1.
Any advice or suggestions on how to fix this problem would be greatly appreciated.
Update
After nearly 3 weeks of new smartfeeds disappearing whenever Feedreader was closed, this problem mysteriously rectified itself 4 days ago. Since then, all the new smartfeeds have survived numerous closings and reboots.
The only change I have made to Feedreader since upgrading from 3.12 to 3.13 is to add one new normal feed to my feeds list and this happened 4 days ago. I don't know how or why, but it seems that this might have been the trigger that solved the problem.
