Just as a side note, I found another possibility that keeps the program from connecting to the update site. If you disable IPv6 on the network adapter so the computer only "sees" the IPv4 address, that's something else to try and check.
- CNTRL-R, enter CONTROL and press the enter key on your keybaord.
- Open the Network & Sharing Center applet
- Click the "Change Adapter Settings" link on the right
- Right click your Ethernet adaptor and select Properties.
- Remove the checkmark from the box for "Internet Protocal Version 6".
- Now OK out of everything. It should not be necessary to reboot.
