How not flight on IVAO.

This was my second flight in the network, yesterday was quite well, but there was no ATC on the route, only unicom. As usual, I tried to prepare it well, flight plan, briefing, maps, weather, charts, frequencies, etc. I flew from Valencia to Toulouse, plane (PMDG 738) prepared for departure, nothing but fly and enjoy the beautiful sunset at 17:00 Zulu time. It is not so good, from the start to waypont SIE I was on the unicom, after some time I noticed, there is ATC control (Madrid Control), I adjust to the appropriate frequency and try to report after entering the control zone, I press the damn key ("space") for teamspeak), and I say: "MAdrid Control good afternoon, RYR40qx fl380 with you" and nothing, I repeat the same phrase 10 times, (my family has already asked me if I was crazy), no response, microphone tested, correct key, fast I look on the phone on google, why not hear me, but no similar results. In the meantime I get a private message that I have to report to him, I think will be a ban for me, my virtual pilot career will soon end. And at the moment in the background of my system, an antivirus scanner is turned on, displayed in the right FMC area, after clicking "OK" my simulator stopped responding, and this is where my second flight ended, after which I went to smoke and drink beer.

Some comments. The microphone did not work because I forgot to turn it on the radio panel. I know, I could write in chat but I did not think about it. The antivirus also forgot to turn off for the flight

I know that I could have done better, better to do it, but my nerves and stress have reached their limits
