I'm sure PSO2 will get a US version some time this century. Meanwhile there is a patch and this is the forum where you can discuss it and get help with issues.
Did the downloader actually complete? Is it pointed in the folder where the file "PSO2_SETUP-1a.bin" is? Because the error is that the installer can't find it. You either need to point it in the right direction or you need to re-run the downloader to make sure the whole installer downloaded correctly.
Thank you i will tell her what you said and see if it fixes the problem if not she will have to re-download it like u said. And if that don't work i will post again.
