Mozy setup assistant causes problem while loading

I understand that today a computer user has to have a practice of data backup and this is very important because of viral attacks, infiltration and any other means, the data could be damaged easily. And so an online backup tool Mozy is installed on the computer. Before running Mozy and recommend this software to other friends, the error is appeared in the configuration assistance process.
“Could not log in
Mozy could not log you in. Please try again or
contact support (support@****.com).
(Error code: -2)”

I enter the login name and password correctly as I use the same to login into the website of Mozy.
Could anyone help me to solve this error? Thanks in advance.
