[QUOTE="mm1352000, post: 1177994, member: 82144"] Hi First, thanks for reporting the problem. Windows is reporting a crash, but the log files show that TV Server is not actually starting successfully. The reason that TV Server fails to start comes from this exception/error: [collapse] [2016-03-10 00:48:51,913] [Log ] [scheduler thread] [INFO ] - scheduler: SchedulerWorker inner exception System.NullReferenceException: Object reference not set to an instance of an object. at TvDatabase.Schedule.GetProgramsForSchedule(Schedule schedule) at TvDatabase.Schedule.ResetProgramStates(Int32 idSchedule) at TvDatabase.Schedule.Delete() at TvService.Scheduler.CheckAndDeleteOrphanedOnceSchedules() at TvService.Scheduler.DoScheduleWork() at TvService.Scheduler.SchedulerWorker() [2016-03-10 00:48:51,913] [Log ] [TVService] [INFO ] - TvControllerException: System.NullReferenceException: Object reference not set to an instance of an object. at TvDatabase.Schedule.GetProgramsForSchedule(Schedule schedule) at TvDatabase.Schedule.SynchProgramStates(Int32 idSchedule) at TvDatabase.Schedule.SynchProgramStatesForAll() at TvService.TVController.InitController() at TvDatabase.Schedule.GetProgramsForSchedule(Schedule schedule) at TvDatabase.Schedule.SynchProgramStates(Int32 idSchedule) at TvDatabase.Schedule.SynchProgramStatesForAll() at TvService.TVController.InitController()[/collapse] I think the cause of the error is that you've somehow managed to get into a situation where you have a schedule that references a channel that no longer exists. To fix: [LIST=1] [*]Open a command prompt with admin privileges (click start button, type [B]cmd[/B], hold down the ctrl and shift keys and press enter). [*]To stop the TV service type [B]net stop TVService[/B] then press enter. [*]Type [B]cd "c:\Program Files\MySQL\MySQL Server 5.6\bin"[/B] then press enter. [*]Type [B]mysql -h localhost -u root -p[/B] then press enter. [*]You should now be prompted to enter the root (admin) user password for your MySQL database. In your case it is [B]MediaPortal[/B] (case sensitive!). Type the password then press enter. [*]Type [B]use MpTvDb;[/B] then press enter. [*]Type [B]DELETE FROM Schedule WHERE NOT EXISTS (SELECT * FROM Channel WHERE Channel.idChannel = Schedule.idChannel); [/B]then press enter. [*]Type [B]commit;[/B] then press enter. [*]Type [B]\q[/B] then press enter. [*]To start the TV service type [B]net start TVService[/B] then press enter. [/LIST] If you've followed the above instructions properly, the problem should now be solved... I hope! [/QUOTE]
