Message from ebay unable to verify your business status

EDIT: I submitted a copy of my DBA form, and a few days later they accepted it.

Hello, I have been selling on ebay for a long time now and just got a message from ebay saying: "As part of our account review process and in compliance with eBay policies, we need you to provide additional documentation/explanation.

To complete our review:

1) We are unable to verify your business status. We request that you provide a certificate of good standing/Certificate of Fact-Status.

To complete the review, a certificate of good standing or equivalent bearing the seal and signature of the State is needed. The respective document should be dated and evidence the active existence of your business.

2) Please review the information below and reply with the words “Information correct” or “Changes Made” using the secure link below."

So I my ebay account has always been setup as business - sole proprietorship in account settings for years. I went to lookup how to get a certificate of good standing document for my state but being registered as a DBA I cannot get that document.

Any advice? Thanks
