You didn't download client_parameters.dll succesfuly. And that's because you didn't make scripts folder in the data folder.
If you get the message "Error while receiving file data.", restart the updater. The server is currently overloaded because everyone want to update now.
When you run the updater, does it say "no update needed"?And if it does, did you delete the .cache file?
I have two cache files; 94.23.237.127.2238 and default, do I delete both?
Problem solvedIf your data folder is missing the scripts folder, you have to make it by your own like Ghosthack notified in this changelog.But do not forget to give the folder all permissions for writing actions!Read AND writeGreetings to all wastelanders
Don't delete default, just 2238.
Here just install my patch in the data folder and it should work fine if u have trouble donwloading the files.LINK
