Open your user.setting file in the Settings folder, and at the bottom set showErrors to TRUE. Then run the mod again and re-create the crash, and it should tell you why it crashed beyond the basic minidump message.

It almost sounds like you didn't set the ability's levelSourceType to Intrinsic with 3 levels in the ability entity file.

thats whats in the file. Anything Wrong? I think its because I dont know how to add a name string and desc string. I only get this error after I change those. I created the ID values in the english.str file and copied the String folder into the Speed Increase mod file too. Did I do something wrong?

Okay, a couple of things:

Your buff is ApplyBuffToTarget, which requires a targetFilter, and a "range" field. The error you're getting shows that you're missing the range field.

Here's an example:

targetFilter
    numOwnerships 1
    ownership "Enemy"
    numObjects 3
    object "CapitalShip"
    object "Frigate"
    object "PlanetModule"
    numConstraints 0
range
    Level:0 5000.000000
    Level:1 5000.000000
    Level:2 5000.000000

Your ability's levelSourceType is set to "Intrinsic". This means it's based off the capital ship's level, which means you need to define which ship levels open up ranks of the ability. An example:

levelSourceType "Intrinsic"
minExperienceLevelRequired
    Level:0 0.000000
    Level:1 2.000000
    Level:2 4.000000

For a generic capital ship ability that opens up at level 1, upgrades at 3 and 5. If you're not putting the ability on a capital ship, you cannot use Intrinsic levelSourceType because no other ship can gain levels.

Simply add a StringInfo block into the English.str file that contains the ID and the Value, for example for your line:

nameStringID "IDS_ABILITY_LASTSTANDELITE_NAME"

You would add this to the English.str file:

StringInfo

      ID "IDS_ABILITY_LASTSTANDELITE_NAME"

      Value "Last Stand"

You would then increase the NumStrings number at the top of the file since you added one.

What the game does is it looks at the ID you assigned in the entity file, then it goes to the Strings file and tries to find that exact ID. The Value field is the actual text that is displayed in-game.

Thanks alot man everything you said worked!

One small correction to your previous post Annatar11,

If you're not putting the ability on a capital ship, you cannot use Intrinsic levelSourceType because no other ship can gain levels.

This is not true as I have moved a ship Ability to a PlanetOrbital and not changed the levelSourceType from Intrinsic. The Ability works like this. I will qualify this by saying that I have Zeroed Level 1 and 2 entries so that only Level 0 has relevant data.

I also think its a bit non-sensical to have it set to Intrinsic and intend to change it to ResearchWithBase shortly.
