<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Dear MCSTAS experts,<br>
<br>
I had mcstas installed and it worked. While I ran a simulation, my computer ran out of power and therefore shut down. It was without power for some hours.
<br>
<br>
When I turned on the computer again, the mcgui did not work. <br>
<br>
I have Mac OS X 10.6.8 (Snowleopard). <br>
<br>
when I try to run mcgui in the terminal, nothing happens. This is all I see:<br>
<br>
Andreas-Nrgard-Larsens-MacBook-Pro:perl andreashlarsen$ mcgui<br>
<br>
<br>
X11 doesn't even start. I can run mcstas with mcrun from terminal. <br>
<br>
Since it worked before, I guess it would solve the problem to reinstall mcstas. How can I do that? I couldn't find any help on mcstas.org.<br>
<br>
I hope you can help. <br>
<br>
Best, <br>
Andreas Larsen<br>
