I can't open EAGLE files with EAGLE 4.15

Hello,

I just downloaded EAGLE files from the HARDWARE page, but I can't open these files correctly.

I can open these files with EAGLE 4.15 on Windows XP, but I can see nothing but blank backgrounds. ???

I'm sorry for trouble you, but it would be much appreciated if you give me any suggestions about this issue.

Thanks, Shigeru

I am going to look into this later tonite, otherwise send me your email address and I will try to send you something.
