"BWA indexes are not ready" is the error i get when i run "add family Y009 reads to human repository"

Hi

when i run one of the protocols in resequencing, i get the following error:

BWA indexes are not ready: Either a current index building is still running or a previous building might fail with corrupt indexes.

why could this error be. i have not changed any parameter and all the prerequisities are downloaded correctly. a snapshot of the protocol is also attached herewith

with regards
