Problems with file type

I have been selling MOBIs and EPUBs for years, but, ever since the last update, I’ve been getting these errors when trying to add files:

The downloadable file [Bookname].mobi cannot be used as it does not have an allowed file type. Allowed types include: jpg|jpeg|jpe, gif, png, bmp, tiff|tif, ico, asf|asx, wmv, wmx, wm, avi, divx, flv, mov|qt, mpeg|mpg|mpe, mp4|m4v, ogv, webm, mkv, 3gp|3gpp, 3g2|3gp2, txt|asc|c|cc|h|srt, csv, tsv, ics, rtx, css, htm|html, vtt, dfxp, mp3|m4a|m4b, ra|ram, wav, ogg|oga, mid|midi, wma, wax, mka, rtf, js, pdf, class, tar, zip, gz|gzip, rar, 7z, psd, xcf, doc, pot|pps|ppt, wri, xla|xls|xlt|xlw, mdb, mpp, docx, docm, dotx, dotm, xlsx, xlsm, xlsb, xltx, xltm, xlam, pptx, pptm, ppsx, ppsm, potx, potm, ppam, sldx, sldm, onetoc|onetoc2|onetmp|onepkg, oxps, xps, odt, odp, ods, odg, odc, odb, odf, wp|wpd, key, numbers, pages, ac3, mpa, svg, ttf, otf

Is there some answer to this problem or do I have downgrade to an older version of WooCommerce?

Thanks.
