I just did it under your account and it worked. Their might be something else which is causing that reaction on your side. Or, could it be in regards to the company name? For now, I entered Test. You may update your account and update that company name field. Your subscription is now ok. You can also get its status from your account. BTW, what did you enter as the company name?
