Hi--I had same probs last week. On to E Bay 3 times and they advised to download anothers programme eg Firefox.  I have had Explorer forever. After 2 days of getting nowhere it came back but with some options missing - but at least I can get some 'stuff' on now. Like you, i was unable to even revise --all went to HTML and no font / colour etc. E Bay said they had not heard of this problem--seems it was more widespread that I was being told ..
