Hello there!

At the time I use Krita to draw, but since yesterday Krita crashed when I use the pipette (?) I wanted to use the same colours as in an other pic, so i switched, got the colour, switched to the new pic, switched back and since then it crashes every time i use this, but only this tool. but if i start it in administrator mode, it works, but then my gallery is gone. Can anybody help me?

I'm btw sorry for that bad english, I'm from germany and nobody here can help me!
