I only registered with Adobe yesterday after realizing that the upgrade SN is not sufficient to activate LR5. Therefore there were no products registered (I registered LR5 now).
I don't have any LR4 information anymore or LR4 installed on another computer. I have LR5 still working on my laptop, though. Would that help? I did find order confirmations from B&H Photo, however, and realized that I actually bought LR3 first in 2/2012.

Would it help if I sent those order confirmations to Adobe?
