Today I just update BRT to SS4 version. It includes Halfsine spiral which is good for me.
But very soon I find a very big problem, I can't use my previous XIN file. I can open it but it's nothing there. I try to open Tools/Copy Preferences, pick my previous XIN file. But BRT tells me that "is not a valid XIN file".
Can any one please let me know how to fix it? Thank you!
