Elf-file stops loading just before InterNiche message

I had a working design until I bought and used

the TSE license. Now loading the elf-file hangs

after printing this line:

nios2-terminal: (Use theIDE stop button or Ctrl-C to terminate)

and just before this line (which was printed

by the working version):

InterNiche PortableTCP/IP, v3.1

Any idea how to solve this?

Thanks in advance,

Jos Groot
