AltSearch -- No AltSearchString.txt file to save batches

I just upgraded to on my Windows 10 machine. I’ve used AltSearch and its batch function for quite a while, but when I did the upgrade, and the upgrade to AltSearch 1.4.2, I discovered I couldn’t save batches from the add-on. Pop-ups kept coming up that I don’t have the AltSearchString.txt file. I tried copying the file from a different computer and inserting it in the proper place in my computer, and it would work while I was in LibreOffice, but if I logged out and re-started LO, I can’t open any Writer files. It immediately crashes. What can I do?
