Salty Grain Plug In won't let me type in fields to authorize

Trying to authorize a plug in by Sample Sumo called Salty Grain. When I try to type in my serial number, username and password (it makes you login via the plug in to authorize) Nuendo maintains control of all keyboard shortucts and does not allow me to type any information into the necessary fields. Paste keyboard commands do not work, neither do right click and paste commands (paste selection not present in some fields.)

Any ideas?

Is the plug-in window set to always on top? If so, try disabling that and moving focus to the plug-in window.

Thanks, was able to authorize it via Sound Forge.
