I've just bought Pushback Express yesterday, after installing it I got an issue when I opened it saying ERROR! The settings file does not exist!, I reinstalled it and I have the same issue.
I looked online if anybody had the same issue, I scrolled through google a bit but I can't find anybody with this issue. The README has no info on this, one thing I did notice is that it installed to the directory Program Files86 instead of appdata where I saw most people have in some older forums, if anybody has this issue please help me if you know the solution!
Here is the link of what the error looked like:
