hello, I went to clean my pc today and when I came back to reinstall the mod pack atm7 it was just not possible, I asked some friends in a live that I follow directly and several reported the same to me, we tested all versions to see if they were going and nothing, we tested other mod packs and they all work normally (atm7 is the only one that doesn't work)

Use the previous version (0.4.20) you can install it through the curseforge website in the files section.

I tried several versions and it didn't work, it just after a few seconds gives the message "deleting files " after saying it's installing forge

I am not sure if this will work as I have not encountered your problem myself, but it has been recommended in the atm subreddit to try using the ftb launcher.

Edit : Apparently in another thread, reinstalling Java could help, although the problem was fixed by repeatedly installing the modpack which doesn't really tell much.

thanks mate! Get it, I need to uninstall and install java, possibly it was a bug that would not allow curse forge to finish the download
