FWIW, if you follow that reset procedure, you lose your stored open/save paths, too.
So if you e.g. use DropBox or a network drive to save your .SLC/.RSS files, you'll have to browse to them once on both open & save for the program to remember that other-than-default path again.
for something like this i would copy the rungs to a library file.
select edit index before importing it.
i do this all the time and i have no issues.
