Okay, I can can confirm that I get the same "dev-mtgb.rar: Invalid or corrupt authenticity information" error when using winrar 3.20. However, I can still extract the exe fine, and if I use winrar 2.90 that was used for making that archive, it gives me the same (byte for byte) executable without any error. So you can ignore that error, the archive is not corrupt it seems. Can someone else confirm that the crack works for him/her ?
