NzbDrone error on launch

It used to work great for the last 2 weeks, but yesterday I restarted my computer (I restarted it alot during that period too) and since then whenever I try to launch NzbDrone.exe it shows this error:

this is the log i found on C:\\ProgramData\zbDrone\\logs:

Sounds like a corrupt config file, any chance you did a system restore at that time? (someone else had the same issue and they did).

You can delete config.xml from C:\ProgramData\zbDrone and drone will rebuild it on start, you will need to reconfigure your username and password (if set) as well as the default port (if changed).

Thank you very much, this worked like a charm.
Any possible explanation to why that happen?

No, not sure how/why that would happen. With the other user I suspect the system restore, but I guess its possible that shutting down while NzbDrone is acting on the xml file could cause issues.

We should be displaying a better error message though, so I have added it to Trello: https://trello.com/c/muxChgBX/362-handle-config-xml-corruptions-more-gracefully

Thanks for the answer, I think that a shutdown is what caused it, happened a lot recently.
