Are you sure the grounds are coming through the basket? Maybe some are getting trapped around the rim of the basket or down in the portafilter, causing them to end up in the cup. Now if you are getting fines through the basket, all you can do is grind a bit more coarse. Later!

BTW, what Krups machine and grinder are you using?

It's possible that you're not tamping with enough pressure, so the grounds are not compacting into a puck. A proper tamp is about 30lbs of pressure, and the grind should be fine enough to form a solid puck of coffee that you can invert and it will all stay in the portafilter. But it's also possible that your machine won't have enough pressure to force water through the grounds with a proper tamp, so that would be a catch-22.
