Charge 3 no longer synching with windows 7

[dcGirlyGirl]

It worked flawlessly until last week.  I can no longer get it to synch with the fitbit.com.

I have:

1) Restarted computer

2) Rebooted fitbit (repeatedly)

3) Deleted data on fitbit to try to start over.  That only led to the time being 4 hours off.

Every bit of advice involves either using a phone app (which I will not do) or installing the FitBit connect from Microsoft.  I argue against that because it was just working beautifully until last Monday!  Unless they have decided to force people to the app, I don't see why I have to install extra apps on either my pc or phone.  Is anyone else having this problem?
