Run the trainer as admin and disable your AV.
What is "AV"
Many thanks for that!! But I have yet to figure out how to use the editor in-game. But I will keep trying.
No worries, using the editor is a breeze!
Select the character you wish to edit.
Open the Character Record screen. (Default [R])
ALT+TAB to the trainer
Click the Player Editor tab
Edit anything/everything on your character you want.
ALT+TAB back to the game.
Leave the Record screen. (I do so by just going back to the game Default [G])
Open the Record screen again, and see that your stats have changed.
Select next character you wish to alter, rinse and repeat.
One note, however. I never raise my stats higher than 25. I went higher once before, and experience some really weird effects. And the reason I suggested a minimum of 100 on Resistances is because there are some instances/spells that can cause your Resistances to be lowered, making you susceptible to enemy attacks and spells.
