I am newbie to salesforce.com development and I am not able to connect using Force.com IDE or Eclipse with Force Plugin.

Everytime i try i get an error saying

Unable to connect to hostname 'www.salesforce.com'

Invalid username,pwd,security token or user locked out.

Please verify/change your credentials.

I just created my login yesterday and was able to create tabs and objects using browser but not with IDE.

I resetted by securtiy token three times and combined with password but still no luck.

Everywhere i search i couldnt find a definitive answer.

Could some one please help me in connecting from Force.com IDE.

I just signed up as a developer and i am not associated to any company.

Any help would be appreciated
