I did the submission process via the website as well.
After I submitted, I just sat back for a couple of days of waiting (more like 5-6 days).
It was a pleasant surprise to see the e-mail saying that my upgrade was approved and within 60 minutes had 2 additional e-mails that confirmed a $0.00 Order and a new Serial Number for LR5.
It worked and I am very happy as well.
Allright, just submitted my form. Guess I'll cross my fingers.
