Hello,

A few things to check (if you did not change anything in your project):

1. Is your code-signing certificate still valid? Perhaps it expired today.

2. Is the timestamp server accessible (perhaps blocked by your new virus/spyware definition update) or is the server down (try another one).

3. Make sure the required Authenticode components are still registered (sometimes Windows Updates unregister the Capicom component).

Hope this helps a bit.

Friedrich
