Report ID: 1784878823
Failure during synching. I wish I could remember the details in the report, but synching stops with the error message. The report said something about some javascript line not defined. Perhaps would be nice if the details of the report remained visible after you click to get the error number. The big picture is this: twice while synching, I got an error message that says if it happens again, send a report and report the number.
If you still get the error, try disabling any security software you have installed or, if this is a laptop, try from a different network.
I followed all your instructions and the error persists. Or maybe it's a different error. I have no way of knowing.
