In the settings you can point slopey's tool to you log files. These are in the folder the game is installed. This may be the Product folder in the EDLaunch folder or in a Frontier folder in the usual program files place.
You are looking for a folder called 'FORC-FDEV-D-1002' and then in that 'Logs'
This only allows slopey's tool to see what system you are currently in (if you have the logging option turned on, which the tool will prompt about once you point it to the log file folder).
If the tool is freezing, is this just a once off after you install, then it's probably some other issue and not that fact it can't see the log file.
Edit due to previous post: The tool does not scrap prices or info from the game files, all of that is submitted by players in the tool so it is working but it's not foolproof.
