Chain problems are always the result of chain maint. issues. I don't think the warranty will cover you.
1) Too much chain tension (should be 3.0 to 3.5cm)
2) Rear wheel not aligned - did you use a chain alignment tool or do the "string thing", the indicator marks on the swing are are notoriously inaccurate.
3) Worn sprockets (should normally be replaced with the chain as they wear at a similar rate and worn sprockets will destroy a new chain)
4) Chemical solvents destroying the O rings on the chain
5) Not lubing the chain at least every second fill up with good chain lube (recommend Maxima Chain Wax or Dupont)
6) Not cleaning the chain to keep sand and grit from building up on it
7) Are the rear wheel sliding blocks properly installed with the indicator marks in a vertical position?
If there is no paint on the side of the drive sprocket (you need to remove it to see the back) this points to an gross misalignment issue causing the chain wear. If only the master link failed/binds then this is the result of a chain installation issue.
