can't open links within EM Client

For some reason I can no longer open links in an email. I could a week or two ago but can’t figure out what may have caused thiis to happen. I check the settings and there seems to be nothing amiss there, and I did not change anything either. What could I look for?

Hi Frank,

Check Default Programs and select your default browser .
then check the Protocols that it uses,
FTP, HTTP and HTTPS should be ticked among others.
if you have other browsers, tick Allow access.
