Isis-Tuflow network licence detached mid-run

[LWar 0]

Hi,

We have a large model running which takes about 12 days. We are 4 days into two of the runs and my PC detached from the network where we have a network licence for ISIS. The run log says:

"Seeking licence for ISIS-TUFLOW-PIPE link...Licence code 4 unobtainable.

Dongle read error code 0

Please attach the dongle and hit return."

I ensured I was reattached to the network but when I pressed return on one run and the model run just closed. The second is still paused awaiting my input, I'd rather not lose 4 days run time if possible. Is there a way to continue running the model having lost and regained network connection?

Thanks,

Lucy
