Hypnotic vst code missing

I bought the vsts monthd ago been using it until today and now the code is missing? I cannot find it on my steinberg either… what can I do?

So - I bought the product again and it shows in my licenser, but I am unable to register it…

Error code:
The USB-eLicenser/Steinberg Key number you have entered is either not complete or unknown.
Registration is not possible.
