Today when I started my Eclipse IDE, all my Android projects have a "Red Cross" next to them!I tried to "Clean" all my projects but with no added benefit! I see no red line in any of my source code (that indicates an error) and am stumped on what to do next. Please help.
Link below for any one who runs into this (likely to be annual as the Android debug key is valid for only 365 days!)
