I read somewhere, that if you try to send files to tempest, but there is not enough space in memory for the sounds, beats or projects you try to upload, then Tempest will simply halt with the text about loading still on the display... You should make sure there is enough free memory to house the files you send before dumping them. There should be a button you can press to exit this freeze though I cannot remember which one... I believe I read this somewhere in the manual or the manual addendum.
