Every time I try to open a tree node I get the following error message. I'm then asked to send feedback on the error to QSR before Nvivo is shut down.

I'm trying to open an "top" node (with aggregated sub nodes) and turn on coding highlights to see where there are gaps in coding within in, but I can't open the node without it crashing.

I've already changed the project so that it only displays in plain text, but this hasn't helped.

Can you help?



Error Message: Object reference not set to an instance of an object.
