I'm returning to Minecraft after about a 3 month departure. I already have the Twitch client installed from my previous MC adventures and I have a few Mod Packs also install from the past. All those still work. I can also happily make a "Create Custom Profile" and install MC from fresh.
However, if I "Browse Mod Packs" and hit the "Install" button on one of them, nothing happens. I've tried the install button from the Broswe screen and from inside the specific mod pack page (top right). Both simply highlight and do nothing.
Thanks in advance for you help.
Now fixed. Logged out the the Twitch app and then re-logged and now works.
