Scheduler not functioning

I am having problem running Amibroker scheduler. Everything looks OK, but it does not start the batch file.

The next run date on scheduler is correct, but it just does not run.

I have been using it succesfully for year before this.

Is there a log file someplace that would give me info as to what is wrong?

Did you create a new test Batch (not task) that also has an option to log.
Run the batch manually and see if it works.
Then schedule the test batch and check it.

There is no useful info that you provided to narrow it. include OS/AB version
