My Sims 2 open for Business has been successfully downloaded onto my computer before but now a problem has occurred. Now when i am downloading the pack the download reaches 17 % then a message pops up saying " A problem occurred when trying to transfer the file 'TSData\ResD\Sims08.Package.' from the media. Do you want to retry to copy the file or cancel the installation?" But when i select Retry nothing happens and moments later the message reappears! Does anyone know whats going on and can you please help me?
