Upgraded to Phoenix beta ran fine for a few days, then one day after a reboot for Windows Update. (Search 4.0 i believe) Had to shut down and restart.
Relaunced RSS Bandit and it failed to load my Feedlist. Tried to recover state by 'Downloading Feeds' (saved to local UNC share) got an error dialog saying - "Feedlist download failed with error: Closed."
Was able to regain the list by loading an old 'subscriptions.xml' saved from right before doing the Phoenix upgrade. It seemed to also make items in 'My Special Feeds" show back up again as well. But then once again after closing RSS Bandit and reloading, no My Feeds. I solved this by doing an "Export Feeds". This (somehow) made RSS Bandit reload My Feeds correctly when it was restarted. Has been working fine since that time.
Attached is the trace.log.
