I'm sorry I don't know where to look for my crashlogs, ive been looking at documents/maya etc, local/temp (where maya crash files would land), program files/autodesk/maya , but i can't find any crashlogs. where do they go after a crash?

I tried to put a checker texture in my hypershade instead of my file texture, the problem i get here is that there is no 'outTransperency' when i connect my checker to the reverse thing... as i followed the tutorial i learned to have my texturefile to outTransperency. However if i would put my checker (connection to the reverse, so checker -> outAlpha, instead of outTransperency) to something else like outAlpha it works in my perspective view, but crashes as i try to render it.
