Thank You!
I updated just the one I wanted and it looks good to go. I installed SDUD01RMAP13.DBR. Is it safe to say that the other file in the directory with SDxxxxxRMAP09.DBR is the older version? and that when a newer version comes out it wil be 14 or 15.DBR? I just renamed the 09 with a .bak file extension just in case it didn't work. Finally its too bad there isnt a converter available to grab the noaa charts from the above link and convert them yourself to the time zero format. That way they would be as current as possible.
Thank You again for your help and expertise.
