ID Safe Chokes on separate logins to same main URL

Greetings,

Acronis.com has two separate logins--one for Acronis and one for Forums. ID Safe will not allow me to create separate logins.

I get this dialog: Warning. The provided username already exists for this site, please use a different username and try again.

Of course, changing the username is not an option as it wants my email address.

Is there a workaround someone knows?

Many thanks,

Ron
