Well shucks!! How frustrating!
That happened to me before. I realized that when I was trying to post something that ended up taking some time,, I would get 'booted' off......so (in case you didn't already know this), I always put a little 'check' mark in the box that says 'Remember Me" when you log on......maybe that'll help?

I'll be in touch soon, I've got to go to an appointment.

There is a forum here specific to "Work Comp" information.
You'll find it in the main menu
Maybe you'll be able to gather some valuable info there.

I hope they (the Insurance) isn't dragging their feet hoping the 'statute of limitations' will expire so they'll be able to say
....'sorry, too late'....
