I don't have access to another camera
As I said earlier, I used a Metz 48 from another forumer on my camera on Sunday and had absolutely no issues with it.
When the flash isn't affixed to my camera, it still shows the same options as it does on camera. I've been reading the instruction manual and my flash unit doesn't seem to be showing options like it does in the manual? Eg When I press the select button, all it will show me is the ev and the number choices for ev, it doesn't show me other modes like ML or Ch etc.
