U dont do noting,that script is auto updatable and it works fine.

I get Error in line 2 with this script :P 0F B7 86 54 01 00 00 8B 0D could not be found.

what CheatEngine Version do you use?
Cuz if you useing Version lower than 6.1 the latest scripts will tell you error in line 2

NOTE:i was using CheatEngine 5.4 and got error on line 2 at every latest Script
then i used CheatEngine 6.1 and got no errors
