BTW there is a difference between Turbo Lister downloaded in Canada to the one you can download from .com.
Since I have been with .com for 15 years I use the US Turbo Lister. The CA version can not reinstall the listings from a US TL coded saved file.
I've had absolutely no problems with TL.com since I installed 10.
I know this does not help you much. Starting over is no fun. Been there, done that more than twice, designed the t-shirts etc.
Perhaps the best way to get around it is to download all listings online into a .com TL? That way you won't lose too much data.
There is also a compatibility program in Windows 10 you might want to fuss with first.
I don't find it efficient at all but that could just me not caring enough to do it again.
Always try it twice, is the hacker's motto!
