[RTTY] MMTTY Question

[KC4HW/Jim]

Happy Holidays!

Trying to help a friend with an ongoing problem.  

Using:  Writelog 11.17
	MMTTY 1.68A
	OS is XP

This is a SO2R setup

When we set this up, we create two installs for MMTTY...

/HAM/MMTTY1 (for Radio 1)
/HAM/MMTTY2 (for Radio 2)

When starting the Writelog setup which calls the MMTTY(s) and they 
come up correctly, but one default because it can not find the *.MDT 
and give a path to the MDT, but it is wrong.  

I have forgotten how to tell or check each occurrence of MMTTY for 
the correct path.  

Can someone give a little help here?

Thanks

Jim/KC4HW
