So Google had told you the exact answer you were asking. If you want to continue the game of Adsense, do what google is asking you and go for a top level domain, which is cheap and easy to register and won't cost you an arm and a leg.
i had a site created in one day and same day i got my site approved for adsense so i think its the doman thats holding u back from adsense.
Remember: one door closes another one opens. You where not planning to just make money with adsense? Be creative and think of other ways to make money.
I plan to apply for adsense following blogs, plz check it and give ur comments ,does my blogs qualify to apply for adsense http://moneyearnmethods.blogspot.com http://informationlearn.blogspot.com
lol Adsense don't like PTC content, So your first blog won't get approved, And the second one seems to have very less content and an inactive blog, a few posts for the past 2 years, I suggest no to adsense with these blogs. Check your PM.
my suggestion will be just get a new dot com website and create 15 pages on that with original articles and the apply for adsense u will get approved sure ...
