Unable to open web links from email messages

[8211davester]

Hi there - am a new poster to this forum.
I have zd installed on Kubuntu 13.10. I received an email with a web link in same. When I tried to open it, nautilus appeared, asked for a web browser launcher to open it. I screwed up and entered the wrong browser launcher location. Now am unable to get links to open when clicking on them. Now that I have located the correct location for the launcher, how do I get configure ZD to open the web links from email messages. Many thanks for any assistance.
