Hi Becky,
Microsoft changed the way it handles keyboard-like peripherals in Windows 7. We do have replacement / upgrade firmware available. Sadly, it can only be installed here in our shop.
However, the new version does include the capability to be updated in the field. So should something like this happen again, you can make changes without mailing hardware back and forth.
If you'd like to send the gear back for a quick update, let me know. Send email to 'sales AT empirisoft.com' and we'll take care of you.
John
