can't save iso to hard drive

I don't know what happened , but I'm now unable to save an image to my hard drive.

it was working fine the last time I tried it but now its not giving me the option to save to HD.

 

In your drop down list of recorders, did you select image recorder?

 

no hd space left?

 

I got it working.
I have to do it differently now, though.

I could do it from nero express before and I'd save it as a ISO,
and the option isn't there anymore, when I try to choose the output file format only a blank dropdown box opens.

now I can only save it as a nero disc image. it still works but its a couple more step this way.
