[Plugin: Rating-Widget] Problems with account generating

Hi.

I’ve tried several times to accept the account generation and activate my account. But i keep getting the following message: “couldn’t connect to host” . Ive entered the capcha code correct and tried on several different computers, but still getting the same error.

Could you help me tackle this problem?
