so just about every 4th time I open thunderbird, it does not actually open. I get a popup that says the profile cannot be found, or something like that, and I have to re install the program. and not the latest version either, it only works if I re install version 60.5.1. I have tried installing a newer version, but the same thing happens, and it won't open. this only happens on my windows 7 laptop, my windows 7 desktop computer has no issues, and is running the newest version of thunderbird. any help would be wonderful, I am ready to look for a new email client for the laptop.
