We got a new computer and its been a while since a played this game. But I know how to install it and everything. Anyways, it stops on the third disc at 60% and a window pops up. It reads: A problem occured when trying to transfer the file 'TSData/Res/Sound/Voice3.package' from the media. Do you want to retry the file, or cancel the installation? No matter how many times I retry, the box still pops up and it doesn't go past 60%. How can I fix this, or is it that the disc is unuseable?
