I'm having a similar problem with one out of my three computers... the other ones work but this one does not... Whenever i open my technic launcher it shows a message saying "checking launcher version" and then pops up a windows helper saying: Unable to download launcher. Please check your internet connection by opening www.techniclauncher.net in your webbrowser. I dont know what to about that... i opened it a million times, reinstalled technic launcher... updated java... I can't seem to get it to work... can you guys help me out?
