Tried with all the following:
DCS=930L
DCS=5020L
DCS-5010L
I also spent an hour with phone support with no luck so far. They've escalated me, but I need to call in again.
Any suggestions are appreciated. But I can't imagine what hasn't been tried. We've reinstalled, shut off all firewalls and antivirus, .... They last asked if I could try a different pc, but I don't have one. This one is a Samsung Notebook with Windows 7.
When it gets resolved I'll share the result.
