Help with single file restore from other machine - failing because of credentials

I am trying out ABR 11, the latest build. So far it is good. But one thing I must have is the ability to restore individual files from a backup. This works fine if the machine requesting the restore is the one that created the backup. What I tried tonight was to restore an individual file from a backup off a different machine to my main computer. The create restore task operation allows me to browse to the network share, load the archive, view the files, and select the file, but then when I return to the restore task creation form it says it can not access it because it does not have the credentials. Now here is the thing, both computers are Windows 7 x64 pro machines and I am the admin on both with the same user name and same password. I tried restarting the console and reentering my credentials and that did not work. I tried entering my credentials in the format {username}@{machine name} and that did not work. So how do I get it to restore files from a backup off of a different machine???
