Need help with downloaded abilities

I need some help. This may sound stupid, but I downloaded some free spells off your site, and can,t figure out how to use them in the game. Can anyone help me?

Andrionin, the problem you most likely are having is the same I expierienced before, you are probably copying/pasting the triggers from the custom spell map to your map. This will in turn cause the spell to not work because the spell will be disabled until you enable all the correct functions in the spell trigger. You have to view the trigger set-up from the Custom Spell map and make them "almost" EXACTLY the same in your map. The only things that can be the same or remain the same are the UNITS and the Regions (if any).

Keep this in mind that using custom spells in another map may not always work if they are in JASS. if this does NOT solve your problem. Please explain thuroughly your full problem, possibly post the custom spell map and your map that you are using the spell on. We will then do our best to help you out. Peaceâ€

I downloaded the bfg 9000 spell, but I have no idea how to use a .w3x file. I'm just starting with world editor, and I can do simple things like make basic maps and scenarios, but I can't do anything complex. My main problem is how to use a .w3x file.

You MUST own Warcraft III: The Frozen Throne It is the Expansion pack to Warcraft III: Reign of Chaos. Most people still have WcIII ROC because they either do not feel like buying the EXP or it may cost too much for them. It is around 25-30$ now and it is HIGHLY suggested that if you wish to use an EXPANSION only spell that you buy the expansion. There may be spells for WcIII ROC, but I myself don't really look, so, I hope you can find some :/ Peaceâ€

All right, thanks. I was planning on buying it anyway, so now I have another reason to.
