Hi, this error is a result of your Toribash folder being set as "Read-Only". You need to go to the folder the game is located in (Games/Toribash-5.22 in case of latest standalone, Program Files (x86)/Steam/steamapps/common/Toribash in case you got the game through Steam), go to folder properties and deselect "Read Only" checkbox.
This may also be related to an ongoing DDoS attack on our server - in which case you'll unfortunately need to wait until the attack is over.
