I signed up for an adsense account few weeks ago. And i tried to active it for my website (it has .tk domain).
But it was failed because the domain is not registered for me.

After it i created a blog (blogspot.com) and tried to active the adsense account for it. But when i try to add adsense gaget to blog it says my adsense account is disabled.

Therefore i updated adsense account with my blog's url. Then google get ownership errors with my blog.

How can i solve this?

Register a new account with a different Gmail and contact details. May be you are victimised for invalid clicks.
If you do not get good US or European traffic, then Google is likely to disable your account in few days as it is potentially a problem to their advertisers (who are usually US or Europe).
Blogs are good, but make sure you target international visitors. Those advertisers of Google have nothing to sell to Sri Lanka.
