Lou: Thanks for the reply. When visiting their site, I did make the effort to make contact via the emails. So far their "info" contact (no support) has bounced and no reply from their Texas "sales" email. I'm also in Texas just down the road on the Golf de Mexico.... If it continues, suppose I'll have no choice but to block the network which is an extreme.... Looks like they ought to monitor themselves a little better, wrong website monitored, bad emails and nobody watching the other emails.... Just had to double my bandwidth and suppose seeing any waste now looms large to me... Best regards, Jack L.
