That's the case with any Steinberg eLicenser software. Most developers won't even give you a replacement. The hard disk licenser is primarily for demoing so you don't have to buy a $25 USB eLicenser just to demo the software (like you do with iLok, unless that's changed). The USB licenser is dirt cheap and eliminates all of this trouble. It's not exclusive to Waldorf.
