Hi there. First of all, no, I've stopped using Skype and other IMs with IRC being the sole exception.
Before we continue, if you haven't set your system locale to Japanese, then do it.
As I said in one of my posts, I don't know if there's any compatibility issues with the English patch as I've never tried it. And do note that the patch I provided in the thread's opening post is for 1.10 and has never been updated. If you don't want to read the entire thread for all possible workarounds, try this post.
If your problem concerns libvorbisfile.dll, try downloading it from
http://www.dll-files.com/dllindex/dll-files.shtml?libvorbisfile OR reinstalling the game and use the .dll files it provides. The Soft Denchi thingy is some sort of runtime programme whose authentication can be bypassed with the crack. Once again, the crack I posted was tested with version 1.10, and I never bothered updating and/or testing it with any other patches, including the official 1.20 update and English patch. It worked fine for me at 1.10 and that was all I needed.
I don't know what those patches do, what changes they make, or what files they modify.
