whenever I try to open the program it says it's connecting to the server, and then just "fails to respond"?
Ok, so the program can't connect to the update server... But can the program download pictures ? Are some pictures showing ?
Because if the program can't connect to the internet at all, it's probably a firewall problem. You must configure your firewall to allow Coollector to connect to the internet. Maybe you could temporarily disable your firewall, to see if it's really the culprit.
P.S: I assumed that your computer is connected to the internet. Because if you use Coollector with your computer offline (it's possible, simply you won't have pictures), you should uncheck "automatically check for updates when the program starts" at the bottom of the window.
