Option to to register after expiration

I would to know hw I can allow my publication to be registered again after expiration currently it jus pops out a message publication expired I want users to be able to acquire a new key after expiration of the first key.

Are you using the global expiration date feature, or the “number of days” expiration feature available in “Certificates” (http://www.htmlexe.com/help/trialtools.htm)?

am using the global expiration option

In that case, I’d rather recommend you to use the “number of days” expiration feature available in “Certificates”, OR you’ll have to wait for HTMLExe 4 since this future version includes a new feature that lets you reset the global expiration state when you publish a new release of your ebook.
