So I've recently been struggling to install and NSP file. I have tried random homebrew NSP's, NSP's I was able to install in the past, and even dumps of my own cartridges. But no-matter what I try to install it just gives me an error telling me either the NSP signature is invalid or just fails to install. I have tried installs on a few different title installers such as tinfoil, goldleaf, tinwoo, and a few others with no luck. Any idea why I've having these problems? I'm on the latest firmware running the DeepSea CFW package.
