It is now over 24 hours since I attempted to register this software. Still no registration email, so now it is too late to try this GAOTD offer. Also, no response to emails I sent to Leawo asking why no registration email. (I gave them the same email I use here ...and I checked the spam folder.)
Sorry Leawo, but this speaks volumes. I will be quite leery of any dealing with this company in the future.
FWIW, this is the first time I've ever had registration issues with any GAOTD offering.
