error when installing tar files

Hi, could someone please help

I get the error message

gamedata is write-protected. Please change CHMOD to 0777 via FTP.

when i try to add games in the ACP and install the tar file games that i've added to the arcade/tar folder

i've edited the number attitbutes to say 777 for both the game data file and the game files and that didn't fix the problem

any suggestions?

thanks!

/arcade/gamedata/ needs to be 0777

thanks, i thought i had set it as that and it still didn't work - our web technician got it working though
