Cannot subscribe for Sketchup PRO

Hi Guys.
I cannot purchase subscription Personal PRO annual. On details page when I enter all info and press continue, I receive this message:
“There was a problem registering your company. Please try again. If the problem persists, please contact our support team.”

I am lost among relevant topics in customer support page in order to solve this issue. Please, help. Thank you.

Do you use special characters in the company name?

No, no special characters.
