All my GSA products wont run - require activation code all of a sudden

I try to run SER, Captcha Breaker, and SEO Indexer.

Hangs for minutes at 'verifying license" then it ask for activation code

Why now, after 5 years working fine, do all of these programs start asking for activation?

Is the license server down? 

Please email GSA directly about your issue. License servers are fine, your license seems fine as well. Though discussing a license issue on a public forum is something I don't do.
