Problems with migration tool

Problems with migration tool

It should be noted that some days I can not update zoho through the migration tool.
The system gives me error like "username or password is incorrect."
Username and password are the same ones used to access zoho and turn out to be right.


This is the script used: zohocreator.exe c:\scripts\Magazzini\Articoli_famiglia.xls <Username> <password> -e giacenze -au Articoli_famiglie Codice Codice

that has until now worked!!!

How can I fix the problem?

Best regards
