Here I will list a few of the problems I have heard about, with some suggested
solutions.

1. Out of string space in module ......

This error is usually caused by not having enough free RAM available for the 
program to use. When running the "Checking for Dupes" option, for instance,
All the callsigns and related info must be kept in memory so that the program
can compare the next callsign against all previous ones. This takes a lot of
memory. 

To make more memory available, try removing some of the TSRs you might have
running. Try to put some of your memory eating programs in Extended or Expanded
memory. All of these my programs work on my 386 computer. I have no TSRs but 
the programs needed to run my programs from the original code are all in memory.
