Texture 2D Load causes crash

[BiscuitGames]

Not overly knowledgeable, mainly just a photoshop idiot. Every time I try and load a texture replacement, I get this.

I'm not sure what could be causing this. Can I get a screenshot of the edit texture window, the version of the game, and if it's free, the name of the game so I can debug it?

Unfortunately the game isn't free. It's UNO on Steam, Build ID 7701702.

Sorry I meant the engine version of the game (you can find by right click->properties menu, not the build version. In any case, I know the unity version of it already and it's probably because it's so old. For now, you should be able to use the old uabe without issues.

You're a legend, the original UABE worked. Have an amazing day!!
