Premium error

Hi,
I'm trying to pay for a premium account, but it says there's an error and "The requested URL could not be retrieved" even through the 2checkout payment option. Tried with 3 different browsers, same error on all of them. Help appreciated.

Thanks.

Seems that 2Checkout have some serious issues. After trying many-many times with the above errors, it went through the steps and made the payment.

Barbas, 2Checkout advised me by email that there was outage that is solved now. Sorry for the inconvenience caused.
