Yamaha DTXpress/DTXplorer/DTXtreme

This one is for Giles but anyone can chime in. 

First, I like the web page. Very nice design. Some of your user kits work
fine but several give me a "Check Sum Error" message on the DTXpress and
don't load. I've tried to re-download and the same thing happens. Any ideas?

Second, when I run dtxchange, I get an error message on the computer saying
"Failed to load control "CommonDialog" from COMDLG32.OCX. Your version of
COMDLG32.OCX may be outdated." I downloaded and installed the vb6runtime
components so that isn't the problem, I don't think. 

Any help would be appreciated. I plan on putting up some more user kits in
the near future.

	Thanks!
