Driver signing problem (dashboard)

I want my file system mini filter driver signed by Microsoft(in dashboard).

When I log in to dashboard, I have to sign to “SignableFile.bin” and upload it.

After uploading “SignableFile.bin”, it says 「your certificate is already used」.

About 5 months ago, I didn’t have to uploading “SignableFile.bin”
and driver signing process succeeded.

What do I have to do?

Sorry, this problem solved.
Problem was about Azure AD account type.
