Hi, thank you for your help.
I tried to search for the offset 0045FDC0 in place of 000045FDC0, but basicaly it's the same number :/
After this i tried to search the string of hexadecimal numbers to modify and i could find one occurence (as you can see on screenshot).
But after the modification i still can't pass trough world invisible limit's.
Here i send you a copy of my original elementclient.exe if you want to see it by yourself.
