New Version doesn't work

Hi Jeff,
I've installed the new version of Simply Fortran but it reports me as unregistered and give a popup saying "a network license token could not be acquired" and the advises that Simply Fortran will shut down in 5 minutes. Any time I try to compile anything, I get the popup. I've looked at my firewall but it's not reporting anything and fwin.exe has full network access. What can I do?
Regards,
Pete
