Hi guys, there was issue today with amazon cloud services hence this error happened. Since it was new year we didn't notice it immediately and then we needed some time to contact amazon support.
Anyway issue is now solved, update was false so now all should be fine.
In future please check change log for new updates, if there is no update in change log then do not update your script!
In case U already updated, you can go to tools/updater and update your script to restore original/correct files.
