Hmm i had 1.3 running online and wanted to try 1.4 so i overwrote everything with the 1.4 files. Joined a game and got the error message. Then i deleted all the files and put my backup in the folders since warezdude said to try with a clean install. After owerwriting the clean files with the 1.4 files again im still getting an error message... and restarting steam dindnt work for me. So what can i still do to make it work ?
