I tried downloading the file as well but it has a password on it. As a result, I took a look myself into enabling English.
I have found an easy to way to enable English, but it has a side effect of causing the character not to spawn (the wrong spawn opcode is sent). I need to find what is causing that issue first. I can fix it with a client patch though, but that is not really the best solution. If I can get it, I'll post the method which should be usable for any modern Silkroad version as it's a lot easier and faster than having to redownload a new Media.pk2 everytime.
