Yes. I have experienced the 404 error.
I have already PM'd the Mod yesterday, and he replied that he tested 2 PCs with IE7 and had no problems. I tested it with 2 PCs in two locations quite distant from one another and had the problem in each case, so I am using Firefox instead with no difficulty. There were updates to IE7 I applied a couple of days ago, so that may be the source, but..... Maybe it has to do with the combination of IE7 and Shaw cable internet? I am not a techie so no clue on my part. Anyone with ideas?
