Data download interrrupted by cras,h data missing from download manager

Having problem with the download of multiple data, they might download, as it seems in the data folder, but do not appear in the SQ4 data manager tab.
​When I try to re-download (add missing data or rewrite data) the download say immediately download finished.

However no data appears in the data manager.

This has happened while trying to download 3 currencies simultaneously, and SQ4 crashed during the download. Had to restart it. At restart, happens the above.
