Comment 1 for bug 741629

Thanks for taking the time to report this bug. It looks like LottaNZB's configuration file (~.config/lottanzb/lottanzb.conf in your home folder) has somehow been corrupted due to the version changes. Removing it should fix the problem. Before doing so, it might be a good idea to copy the content to this bug report as it might help to figure out what went wrong and prevent such problems in the future. If there is any sensitive information (passwords etc.) you should remove them first.

What was the problem that caused you to go back from LottaNZB 0.6 to LottaNZB 0.5.4? And why did you later decide to upgrade to LottaNZB 0.6 again (since the messages you posted are from LottaNZB 0.6)?
