FearLess Cheat Engine

Hi! I've been trying to use the All value type, but whenever I click "Scan" the bar fills up a bit, then the bar resets and nothing happens. Can I have a little help? I'm using 6.8.1

Check the "All type" scan setting in the CE "settings->scan settings", check that something is checked; usually "4 byte", "float", and "double" are used.
