InDesign shows Regular Font text as blank but shows in Italic, Bold etc. Please Help

I have tried reinstalling this particular font (refer to image) and reinstalling InDesign. The regular font is still showing up as blank. When I open documents with that existing font or even create a new text box it is completely blank. It only shows when I try typing in italics, bold etc. 

I've also tried previewing the document on my collegues computers and it works for all of them - they can see and type with the regular font. Just doesnt show on mine. 

Has anyone else experienced this issue?

Please refer to image for example.
