Plesk Scheduled Backup stopped working! Please help!!

[PraxitelisI]

Hello,

I Have WINDOWS Plesk 9.5.2
Upgraded MySQL from 5.1 to 5.5
Plesk Panel is working perfect (checked everything) - all websites are ok
The first day AFTER update the scheduled backup (daily backup) worked perfect without any issues!

After this day, i noticed that it STOPPED working at all!
I tried to restart all services, rebooted pc, killed all current scheduled_backup tasks and still nothing!

My daily backup folder has only backups until 11/11/2012 and nothing till that date!
How can i check what is wrong? How can i find error logs? What could be happened suddenly to my Plesk Scheduled backup task??

PLEASE help... i really worry about my domains!
