For a while I have been getting the "Can't connect after three attempts" dialog. Googling around, this is often put down to the USB RS-232 adapter. Can't be that because I'm using an old laptop with a DB-9 connecter built in. Dismissing the dialog and trying again eventually gets it connected. From then on, everything's happy.
Used to work fine. I'm not 100% sure, but I think the problem started when I upgraded to TunerStudio v3.
Yesterday I updated to the latest release for Linux (3.0.18). Doesn't seem any different in this behaviour.
I'm running Debian Linux. I was running the openjdk-8 JRE; tried downgrading to openjdk-7. No different.
The firmware burning tool works perfectly as does the mini-terminal.
Any ideas what I might do to get this working reliably again? Less desirably, is there a way to tell TunerStudio to keep trying? It's a bit fiddly unticking the "Work offline" menu item repeatedly.
