I know how that feels. I tried to post on the forums here earlier and when I tired to post it, it failed! So i tried to post again. Same thing happend, IE said page could not be displayed. However, I was lucky and it acctually posted my comment. I have also experianced it many times in blender
today!(I forgot to save and my computer froze.) Word has done this numerous times as well and crashed without warning. The auto save was every ten minutes, so wouldnt ya know when the last auto save was? Too long ago. Ah well, so I changed the auto save to every 2 minutes

.
Think outside the box.
To go on an adventure, one must discard the comforts and safety of the known and trusted.
