Ok I have simillar problem,
Extensions/MyUpdater (MIssing parentheses in call to 'print'. Did you mean print'('[FANTASTIC] Pluginexecution failed')? (pluginpy, line 57))
I have tried to overinstall it but for some reason system do not even attempting to start instllation
Is there any way to uninstall it and re-install it?
MyUpdater is not shown in plugins
I'm very beginner so if there is any way to fix it before reinstalling openatv please help step by step
