It can be confusing.  Like you don’t have enough to do on the violin, you’ve got a piano doing a whole different thing—and somehow, you’re supposed to fit your part in.  I get it. 

When I was first trying to play duets with my teacher, I found myself confused by what I was trying to play, & hearing her play something different threw me off.  Like all things violin, you’ll get better at it with time.  But at the root of it is the rhythm thing—it’s your anchor.

In your version, it looks like the piano just maintains a steady quaver pattern for most of it, which can make it easier to focus on counting just your part. 

The problem with trying to play with a pre-recorded track is that you may not know your part well enough yet to play at the recorded tempo.  A lot of practice time is spent 1) slowing things down, 2) breaking music into chunks-- a few measures (or a few notes) at a time.  It can be really difficult to play at tempo if you haven't got the tune under your fingers yet.

Before playing it, I’d recommend counting your part out loud while tapping the beat out with your hand.  Since the beat is in crochets, you should always count the numbers, and any quavers upbeats you play.  So, for the first 11 measures of your version (bold is the notes you play, unbold you have rest, underline is sustaining note), it would sound like this: 

1  2  3  4 | 1  2  3  4  &| 1 & 2 & 3 4 | 1 2 3 4 & |

1 & 2 & 3 4 & |1 2 3 4 | 1 2 3 4 & |1 & 2 & 3 4 &|1 & 2 & 3 4 |

1 2 3 4 | 1 2 3 4 & |etc.,

While you’re counting it out loud, you should tap you hand on a table (or something) the 4/4 beat 1 2 3 4|1 2 3 4|  So, you’re hand is always tapping on just the number—the beat. 

After you've done that, you should try to play the first few measure, saying your counting out loud just like you did above.  If you get confused, slow the tempo down. 

After (after) that, then I'd try to play with the track.
