so, i just got prompted to upgrade to 2.0 (from 1.x), and now it's asking me to "link devices". what am i supposed to do here? I don't want to link any devices - i just want it to do exactly what it was doing before i upgraded. my choices are these: 1) link a device already running sync 2.0. i don't have any other devices running sync 2.0, so this is out. 2) this is my first sync 2.0 device. this is asking me to create an identity. but i already have an identity, whatever i was using to sync my pre-2.0 devices. why is it asking me this? 3) uninstall what the actual f? why can't it just cleanly upgrade from 1.x?
