Hi Michael,

I had MOI reinstalled and now it works fine!

> Is there any crash report generated in your %TEMP% folder?

So, I checked %TEMP% folder but it was after reinstalling MOI, & nothing was there!

My machine is old, but I believe its hardware is still fine & it is not affected by dust (that's what I believe!)

I believe windows might have corrupted! My problems started to show up after I tried to remove Fusion 360 from my machine!
Here I had talked about it: http://moi3d.com/forum/index.php?webtag=MOI&msg=9952.29

Anyway for now MOI is working :)

And soon I believe I will reinstall Windows.
