[Solved] Stuck in Loadscreen. Blackscreen on Preview

So i wanted to coniniue on one of my GD projects, updated to the newest version and now when the Preview load is at 100%, nothing happens. Just black screen with that 100% load.

Any idea why its not working?
Btw, when i try to use the Online editor on the webpage, its also not working. Could be something wrong with javascript?

Its been a while, since i was writing here (been diving into Panda3d the last couple of months)

E: Reinstalled it and nowit works again.
