Parameter is incorrect when launching admin

I’ve suddenly started geting this message when I try to launch the admin console for openfire.

The full message is:

http://127.0.0.1:9090/index.html

The parameter is incorrect.

I can can open the browser and type that address in, and it opens without problems. And Spark runs just fine.

I’m just curious as to why this might happen. I’m thinking some sort of registry error, but when I reinstalled openfire, nothing changed.

Anyone have any ideas?

Much appreciated.
