File uploader tool has stopped working

I can no longer access any of my Zoho accounts through the File Uploader tool.  Do you know any possible reason for this?
Earlier it was working but now i am not able to login into it.
Your team has suggested us this tool to bulk uplaod the files
from the hard drive via an exe file. You have provided the below given link to us to download it :-
