Don't type xgroove~ into an object box.

Seriously without knowing more one can only guess.

What does it say before it crashes, or can't you see?

Afaik xgroove~ is a variable rate sample playback unit. You can do the same thing in a number of ways that might be more flexible and instructive.

First I would experiment with loading samples into a table. Use the -resize flag and openpanel, its really easy that way.

Use a [tabread~] or [tabplay~] to play back the sampled groove by applying a simple phasor~

Then apply various line~ type segments combined with osc~ signals to get the kind of backwards and forwards scratching effects and vibrato you can do with xgroove~

Other units to explore are vline~
