Blank Composition Preview Monitor Input Selection and Output Transformation

[pewpewpew]

My composition and preview monitors went blank for no reasons.

The input selection and output transformation view as well.

I tried reinstalling arena again and it came back but once i restarted the pc it went blank again.

Anyone knows how do i resolve this. Thanks in advance.

A screenshot of the Resolume window might help, I'd guess the opacities are turned down somewhere. Likely the composition master, on the top left in the UI.
