I have no idea why IE is complaining about the BOSSlog, as said above it is just plain HTML. The masterlist not being found can be a few things, most of which are covered in the readme.
Yes, I checked the readme and it dosen't mention the Critical Error: BOSS\masterlist.txt cannot be read! There is one that describes my issue though now that I went and double checked.
?Message: Critical Error: filename cannot be read!
?Issue: Your masterlist.txt does not exist, or is in the wrong place.
?Solution: Make sure that your masterlist.txt is in your Data\BOSS folder, or use the masterlist updater to download a new masterlist to the correct place.
My problem is that the masterlist updater is not creating a masterlist.txt and I'm wondering if it has something to do with IE preventing something.
