the chief command for thsi tool box is fastq-dump, which downloads the SRA you are looking for
Identifying the right SRA name is an issue, so it's good to be able to do a quick test to see if you have the name correct via
fastq-dump - X 5 -Z SRR390728
"-X 5" just downloads the first five reads, while "-Z" send them to STDOUT. If this doesn't return an error you can go ahead and download via
fastq-dump --split-files SRR390728
