Getting an error trying to import a task list

[Mr. Yellow]

Hi! We are trying to make a script with "eraser importtasklist <name of the exported file with tasks> and when, in cmd, we run this line, it closes without importing anything.
Is this some kind of "known error"?
Thanks!

EDIT

The Eraser version is 6.2
When i run the command, another black screen pops with this text:

Specified methos is not supported.
at Eraser.Manager:RemoteExecutorClient.RemoteExecutorClientTasksCollection.LoadFromStream(Stream stream)
at Eraser.Program.CommandImportTaskList(ConsoleArguments args)
at Eraser.Program.CommandMain(String[] commandLine)
Unhandled Exception: System.NotSupportedException: Specified method is not supported.
at Eraser.Manager.RemoteExecutorClient.RemoteExecutorClientTasksCollection.LoadFromStream(stream stream)
at Eraser.Program.Command.ImportTaskList/ConsoleArguments args)
at Eraser.Program.CommandMain(String[] commandLine)
at Eraser.Program.Main(String[] rawCommandLine)


After that, another message pops with "Eraser stop working"

Some thoughs?
Thanks!
