Greetings RevivalRO Players, We've got many players complaining about the patcher and how anti-viruses stops it and/or it simply doesn't work at all! We're sorry that you had to go through this experience, we've moved to use a better patcher which simply. works! There would be no need to re-download anything, however you will need to download a 4MB sized file and extract it into your game folder, if you're a new players or can't see a warning message in your patcher, then cool! yo
