I do have MultiBit already (to make it run, I had to install bulky Java again, after I had uninstalled it just a few weeks ago, duh). Electrum didn't run here at all. I sure would have liked to handle it the more professional and securer way, with the database. Maybe I'll go at it slowly, importing a few spare hours every day, though that will make importing the final two gigabytes last for a week probably.

Regarding the torrent, I always thought, if a torrent file had been tampered with, it would be rejected by trackers. But I trust, if it worked like that, the good people here would have used it that way already long time ago.
