Hi Diane,
I don't know what might have happened, other than prior 
contamination as Ed suggested. I've been using PVC-E forever 
with no failures. I've never been able to get satisfactory 
results without something holding the top and front against 
the key. I use masking tape, one strip around the front, and 
two on the top.
