購入済みのアドビソフトが急に使用できなくなりました。

引き落としがある場合は、その内容を元にして、サポートへの調査依頼を行うほかありません。

クレジットカードの情報を元にしての確認はサポートでしか行えないためです。

（明けた直後は大変混雑することが予想されますが）

Click the chat icon at the bottom right of the page to open a chat session. Typing AGENT into the chat window should connect you directly to a CSR rather than the AI.

If the CSR refers you to the forums, insist on speaking with a supervisor and keep moving up the chain until you get someone who knows what they are talking about.

You can also search for Adobe customer support using your favorite search engine. This will normally provide you with a regionally appropriate phone number that you can use.

Be aware that because of the pandemic, wait times are far longer than usual due to reduced staff and higher demand. Please be patient with the people to whom you speak. Like you, they are feeling a great deal of stress. A little patience and understanding will go a long way to helping you in your particular situation.
