digital signatures unknow

J

Jan Schuster

Hello,

when i start a digitally signed infopath-dataset (parts of the form are
signed) a message box pop up with the following message:

One ore more digital signatures in this form could not be verified. Parts of
this form are digitally signed and cannot be modified. To modify those parts
of the form, remove the associated signatures.

In the View of the signature i saw, that the Signer is unknown (???) and
Status is Invalid.

The purposes for the digital certificate are i. a.:

- CodeSignature
- Digital Signature

I thougth, that is enough.

Know anyone something about this. I'm thankful for any help.

Greetings Jan
