Have tried deleting the LaunchNet7.exe_Url_ folder and have replaced the LaunchNet7.exe but am still getting the same error. I also deleted the entire NET7 folder and reinstalled and then tried to launch without patching as I have a server list before i update but i then get a proxy error which forces me to update which then reintroduces the original error.
I got around this by making a copy of the NET7 folder, then i updated the launcher which updates the proxy7.exe to the current version (1.98). I replaced the original proxy7.exe with the current and used the copy of NET7 folder to run the game.
