Hello there, I've started some months ago a new mod that I will probably released soon, wich is a Star Wars Battlefront II mod for SA. I've starting convert ships, maps, and weapons but I've encounter an error with TXD Workshop. When I open this texture:

There's no problem but when I click on properties and then check the case "compressed" an error window appear saying "Floating point division by zero". And I don't understand why this appear because the image is in standard size (512/512).
I hope someone can help me.
