[Info-vax] OpenVMS 6.2 on SimH hangs on boot

[Single Stage to Orbit]

Years ago I got OpenVMS 6.2 up and running using SimH. 
I have just tried to boot it up over the weekend to find some files
that I need to get over to OpenVMS 9.2-1 on x86. 

Unfortunately, it now hangs at this line:
"%UCX-I-DEFINTE. Defining interfaces"

I think this might be because licences have expired but I was given to
understand that I still could login as SYSTEM even if the licences have
expired?

Any ideas how I can get past this so I can get at my files? I left it
running overnight and it was still hanging. 

Many thanks,
Alex
