Preview app crashing every time..

Hi guys, can anybody please help... Every time I open preview to view an image I keep getting this same image:

" The last time you opened Preview, it unexpectedly quit while reopening windows. Do you want to try to reopen its windows again? "

Think this has started happening since I opened a large .psd file to view in preview an it just crashed and ever since the same message...

Many thanks in advance
