So I have uninstalled Launchbox and installed it again, but it still happens. What I can du is just delete the plantorm and inort it again and it works. Its very random, and I still consider this a bug. But I now just import platforms, one at a time. Only have Clearlogos down load and iff it dosnt work, delet an do it again. Once I have a handfull of platforms I let launchbox download the art that I want.
Its a little bit of a hassle, but then again, its not that will be importing new platforms al the time 🙂
Anyway faeran, thank you for taking the time to helping me.
