I have been having trouble too. Today I used my laptop instead of my iPad and went to the Spanish sweepstakes site. It did not work at first for me, but what I found would work was to login first using the login link in the black menu bar at the top of the site next to the search box. Once logged in, I would then press the enter button and get the message, "Thank you for entering." This same strategy worked for my parents today as well. It's interesting because earlier I could not find the login link at the top of the English sweepstakes site and there was no enter button either. I just checked on my iPad and I don't see the login link on either site. However, I can presently view it now at the top of both of the English and Spanish sites on my laptop and the enter button is now on both as well. I really don't know if using the login link to login first improves the success rate of entering but thought I would post in case it does prove to be a possible solution. Good luck, everyone!!!
