Hi Silvia,
I am sorry, you are really unlucky !
When you say you opened my simulation, what do you mean ? For instance, could you read the
results in the result interface? could you launch it again ? Did it run ?
Could you please send me the file debug.txt located in the same folder as the isis-fish.bat file (the one you use to launch ISIS) ?
If I can not figure out what happens based on your answer and the debug file, I suggest we try and skype at some point so you can share your screen and maybe I could understand what goes wrong.
