PokeTEX not working?

[LontaBeans]

Okay, I'm trying to edit the overworld sprites in HGSS. If it makes any difference, I've been following 2and2make5's tutorial of it. Whenever I open up the ROM in PokeTEX, a few seconds later "PokeTEX.exe is not responding". Is there any reason that this is happening that you can think of? Thanks, and please try to write to me ASAP. :grog:

Okay, I know what I did wrong, but now when I insert the sprite and try my game, it freezes.

Could someone give me a brief tutorial? All of the ones on YouTube aren't helping.

I'm probably messing up, but this is what I've done in order:

-Open .btx in TileMolester, save as .poke.

-Open .poke in PokeTEX

-Open Rom (1.narc)

-Find edited sprite (sprite is already in, just not colored)

-Edit palette (Here's where I think I'm going in the wrong direction.) The palette doesn't save when I export the .poke. If I reimport it, it just turns up plain black.

-Rename "1_842.poke" to "1_842.btx" (not sure if I should be doing this, but as mentioned about the palette won't save.) If I try saving the Rom an error pops up.

-Save, make narc, reinsert.
