I'm assuming the new user account works and you're trying to copy files from one account to the other. (If this isn't the case, ignore this)
On the C drive open the Documents and Settings folder. There should be a folder for each user account. Open a window for both your old account and the newly created one and have them both open side by side. Copy My Documents, Favorites and Desktop from the old account folder to the new one (it's OK to overwrite the files if there is nothing new in the new account). As for email, it's a bit trickier.
Outlook Express: Open OE and set up your email account with the correct settings. Go to File > Import > Messages to open the import wizard. Take the defaults up to where is asks where the messages are located -- click Browse and browse to Documents and Settings > *old user name* > Local Settings > Application Data > Identities > *some off-the-wall folder name -- the only one there* > Microsoft > Outlook Express. Click OK and use the defaults from there, it will import email from the old account to the new one. For address book use Import > Addresses. It will open a menu to find your address book -- browse to Documents and Settings > *old username* > Application Data > Microsoft > Address Book and click Open. It will import your addresses from old to new.
(It's been a while since I've actually done this so the process may be a bit different but not much if at all)
Outlook: Set up Outlook account w/ correct settings. Click File > Import and Export. Choose "Import from another program or file" and click Next. Choose "Personal Folder File (.pst)" and click Next. Click the Browse button and browse to Documents and Settings > *old username* > Local Settings > Application Data > Microsoft > Outlook and import your *username*.pst file. Replace duplicates -- there should be none to begin with. Import under Personal Folders and include all subfolders. It will pull all email, contacts, tasks etc.
Hope it helps.
