I dont think its human error/accident of buying the textures.
I've waited for the page to load which I waited and leave it for about 3 minutes to load.
Actually I just clicked the 128x128 hand texture of which I already have it. And for the other textures, I just right click and saved the pictures. I never did entered into any other links except the hand texture.
And if ever I clicked the purchase link, I should be directed to torishop link and there should be note like "You have purchased <item>" at the top of torishop.
