Error 64 means "Bad Filename".  I don't think this is correct, but more 
likely some sort of memory management problem.  I have virtually no Win98 
experience, and none with RITTY 4.14.  I have no idea how much memory the 
RITTY takes, or how much is left for NA after RITTY is loaded.  My first 
advice would be to look at how much memory is free after RITTY is loaded, 
and also try loading NA in RTTY contest configuration (but with RITTY not 
loaded) and do a MEMORY command (i.e., type MEMORY in the callsign field of 
the logging screen).  Two numbers appear that the bottom of the 
screen.  Ignore the DS number, but HEAP is the amount of unused DOS memory 
left after NA loads.  For example, on my Dell P-200, Heap=35474 with NA 
loaded normally.  You might also try the "-C" command line switch (inhibits 
use of XMS memory).

I don't mean to be glib, but you're really on your own running this stuff 
under Win98.  Each succeeding version of Windows has less and less 
compatibility with "real" DOS programs.  RITTY is particularly bad in this 
regard as well.  For example, it cannot be run under WinNT, and even older 
OS than Win98.

Some day we're all gonna be scraping around for old DOS disks...
