Sounds like you have some corrupt settings files.

Check your cue list clock source is set to "internal-relative" for space bar to advance cues

Thanks for your answers.
Yep, internal relative was the culprit for the spacebar.

This is what the cuelist looks like.

I am suspecting a missing font, but I have no idea which one. If I click on the boxes I can read the text while it is being edited, but once I am done it reverts back to these squares.
