Please see
http://Errors.KVSTool.com/ under "
'Error Requesting Data: (Various)' after upgrading to the latest version (previous version worked OK on the same machine)".
I don't have the firewall enabled so the program exception is irrelevant.
I have no other internet connection issues, except for KVS availability. And this began only after the upgrade.
I'll wait for the next KVS upgrade and try again.
