first thing: is your computer connected to the power supply? if not, plug the cable in!

ok really... i have no idea how we shall help you without any further information to what your actual problem is so i suggest you go and search for the many tutorials out there which explain a lot. there is even a sticky with an overview of all the useful threads.

Upload you mod so we can determine the problem. And look at the Blackulus Mod for help.

To edit items in abilities you have overwrite the original with your moddified version.

Example:

BuffBlueprint {
    Name = 'HEMA01FireAbilityDisable',
    DisplayName = 'Fire Abilities Disabled',
    BuffType = 'HEMA01FIREABILITYDISABLE',
    Debuff = false,
    Stacks = 'REPLACE',
    Duration = -1,
    AbilityCategory = 'HEMA01FIRE',
    Affects = {
        AbilityEnable = {Bool = true,},
    },
}

To change the values of this ability you would hook a file with the following:

BuffBlueprints['HEMA01FireAbilityDisable'] =  {

#mod values as desired
    Name = 'HEMA01FireAbilityDisable',
    DisplayName = 'Fire Abilities Disabled',
    BuffType = 'HEMA01FIREABILITYDISABLE',
    Debuff = false,
    Stacks = 'REPLACE',
    Duration = -1,
    AbilityCategory = 'HEMA01FIRE',
    Affects = {
        AbilityEnable = {Bool = true,},
    },
}

If you check your demigod log you should see it saying it hooked your file, tried to load your ability blueprints, but failed due to duplicate blueprints.    You might check my mod a few post below this to look at setting values in some of the character character files.

Oh thnx. I will reply if this goes well

Now that you have the folders named correctly you still have to do what i said to change/overwrite blueprint values. 

You can check your log file to verify all your files are being hooked, search for 'hooked'.

I cannot find the log file anywhere

And if you check the updated version, you will se that i have created ability blueprints.

The demigod log file is in my documents -> my games -> gas powered games -> Demigod -> Demigodlog.txt

There should be plenty of errors in there for you to address.

debugger? did i read debugger? which debugger?

perhaps you should begin with something easy. like hello world? seriously. if you cant get such easy things to work with all the help in this forum how will you be able to go on? do you have programming experience?
