Well, I just tried again. First I ran Error Killer for a complete resgistry and windows shortcut scan. It found 8 registry errors and 3 shortcut errors. Hit Fix Problems and reran SH4. Low and behold it's now loading as it should. Sorry about that stupid question.
:hmm: Weird way to fix loading of SH4 but it worked.

Why, I've no idea.
Here's the link to this great program...

It's not free but worth every penny you pay. I highly recommend it... if that means anything.
Edit: What they say is true in their opening page. It's NO Bull.
