tried both and i also deleted whole folder and redownloaded to add i just noticed that gameguard folder is not there after redownloading
it has gameguard.des but not the gameguard folder. it doesn't update a folder when i redownload or launch launcher.
idk it might have been that because my antivirus updated, but i just did system restore right now and i can log in now.
nice, if you have problems again make sure its turned off when you launch rf because some anti viruses think game guard files are a virus.
