Still having trouble with Office 2007 Enterprise on XP SP2 computer?

I have just installed Office 2007 Enterprise on my computer and no part of it will open. Since installing, I can't open any word documents (including the new ones I've created), pictured or anything else, and I can't even open the components themselves through the start menu. When I try opening a newly created Word 2007 document, nothing happens. I tried to use the "open with" command and select Word 2007 and I get the message "Windows cannot find (document name) make sure you typed the name correctly and then try again." Then it tells me I can try using the Search function to locate it...

Any ideas?

One more little bit of info that may or may not have anything to do with the problem... It was a clean install. I installed it on a computer that use to have Office 2003 but it had been freshly deleted while leaving all the 2003 docs and such that had been created with it...

Yes, I was able to register it without a problem... Unfortunately, Microsoft has not been a lot of help with the issue... I'm hoping to find someone that has had a similar issue around here...

Where you able to register your copy of office 2007?
