Per Mitya's request by PM, I sent a message to a new address at VBA yesterday. I didn't request a trial key, as I had already done so in the past, & figured that such a request was understood & needn't be endlessly repeated. Today I heard back from VBA's Dmitry Sorkin. No trial key was provided. Instead, I was advised that requests for trial keys should henceforth be sent to... email@example.com Ergo, it seems my unanswered prior requests for trial keys went to a black hole & count for nada. However, I am quite happy with Avira so it's no big deal. I'm done here.
