Are you sure it's because of the changes? Did you revert back and try again? erminig is great but it's capricious, for example it works great on my 3G/3.5 connection but it always shows a bug-detected-message when trying to sync on Wifi, maybe it's the Wifi here, I still have to try it at at another one but this is a thing that bugged me for an hour or so until I noticed.
