buttons stop working

I'm working on a simple "sigh!" prototype to display basic interactions, it's just a bunch of buttons with rollover, click and idle states. It all worked fine until Edge crashed (which happens frequently I must add) and now my buttons don't work at all. The actions are still there but they don't work on export. One of the buttons makes the cursor change to the hand but it never displays any other states but the idle one and another two buttons are permanently on the down state and don't change the cursor when rolling over. I've restarted edge to no avail. This was supposed to be a quick job!
