So I tried deleting the "LaunchPad.Cache" as some of you suggested and now Launchpad will not launch at all.
Make sure the launchpad has all permissions to connect to the internet. If yo need further help: http://help.daybreakgames.com/
Took me a while but i finally remembered what you have to do. It's your internet options if you're running dc universe on your pc. Go into control panel and go to internet options. Choose Advanced tab. The choose reset internet explorer settings. That's it!!
Same Thing just happed to me, I tried everyone else's method and it worked until I logged of. Now Its doing the same thing
if you have multiple or just one firewall you have to allow permission for each antivirus and security app or it won't work. also you may have to clean install if a virus or corrupted game files. i had the same errors until i set the launcher as a permitted app in ALL antivirus firewalls.
You can do all they said but nothing is going to help it out. It is some internal error...they need fix this because it happens to thousads of people i think.Someday ,someone may fix it....who knows
