I am running 2.14.2 on a Windows 7 machine. I suspect that the newer
versions of JTAlert don't support win 7 now.

I have tried disabling my ZoneAlarm a/v prog but it didn't help. On
one occaision the sound and dx lab communication worked but the next
time I ran JTAlert it had stopped working. Probably a win 10
upgrade would fix these issues.

managed to go back to an earlier version by just running the
earlier install file over the top of the later version. It all
seemed to install OK. Do you still have the earlier install
For the guy who asked why...the sound alerts would not work on
the later version and I also had issues with the UDP not talking
the DXlab so I went back to the fault free earlier version.

That version is?
Regarding the sound problems, that is likely a UDP issue as
well. JTAlert itself doesn't produce sounds, but sends a UDP
command to the JTAlertV2.Manager.exe process which is
responsible for playing all audio. JTAlert doesn't talk UDP to
DXLab, that is purely DDE and TCPIP, and both of those are
handled by the same manager process.
It sounds to me like your Protection software (what are you
running?) didn't like the newer builds of JTAlert and was
blocking all the network traffic to/from the Manager process.
There is nothing I can do about overly aggressive or configured
