Issue with RNAseq: Bacteria training data

I am going through the above tutorial, and added the files to my history. When I try to map with bwa-mem the new files in my history just stay red and comes up with- Failed to communicate with remote job server.

Can anyone help,
Cheers.

Ok, my bad. Gave it an hour and retried. all went through.
