I'm having issues with downloading the Tekkit launcher. I used to have it years ago on a dif pc but I decided to download it again as vanilla MC is getting boring. but when I go to the site and download the launcher and open it, it shows the logo and a progress bar but it never moves and says "Downloading server asset: open sans+cy" but never seems to make progress. I've left it for days once and it still did the same thing. No progress was made. Any and all help is much apreciated.
