Your existing Google Adsense account got disabled ? I am sorry, I guess it will be frustrating, but there is a very little chance of re-instating it. I dont think Hubpages can do anything with respect to disabled Adsense account.
You can appeal to Google, asking them for reasons and you can put your case, but very little chance of reinstatement. Sorry for being discouraging, but this is the truth - please see the following thread where a fellow three year old hubber had his Adsense account disabled - http://hubpages.com/forum/topic/85195
Anyways Goodluck to you.
