Rekordbox not launching

I don't have any rekordbox compatible products plugged into my computer at this moment. Just trying to launch rekordbox from my desktop (Windows 10 - 64bit). Rekordbox comes up with the login then I login - it goes reading tracks etc - then the screen disappears and nothing ever happens again after that. Then if I go to task manager to remove all the processes and then reopen, this time nothing happens at all and I must go to appdata and delete the pioneer database to get it to relaunch and do the same exact thing. Is this normal? Just want to get into rekordbox to analyze music without any products plugged in.
