Upgraded from 6.04 to 6.05. Now Itunes will not open at all

Question

I had 6.04 on an XP Pro PC working fine. I did the suggested upgrade to 6.05 and the install appeared to go fine, but when I click on the program I get an hour glass for a few seconds and then nothing. I have repaired and reinstalled and same thing. PC is kept very clean with no viruses or internet garbage. Any suggestions?

I did as instructed and set up a new account with admin access and it worked fine, went back to my original account which also has admin access and it still locks up and if I ctrl alt del and check the applications it says not responding
that's the result i wanted to see. that's suggesting that there's a problem with the itunes preference files in the account which is getting the "Not Responding" freeze. (there's a different set of preference files in each user account, so different users can set different itunes preferences. that's why you can have preference-file-related problems in one user account but not in another.)
we can usually get past this by rebuilding the preference files in the problematic account. here's how we'll do that.
quit itunes, and log into the account with the freeze. now we find the preference files. they're in hidden directories on the PC, so you might have to turn on "show hidden files" to find them. (Right click "my computer", select open, select Tools menu -> Folder Options. Select View tab, "show hidden files" radio button is in the center scrolling panel.)
first find:
C:\Documents and Settings\<username>\Application Data\Apple Computer\iTunes\iTunes.pref
... rename it "iTunes.pref1" and drag it to your desktop.
next find:
C:\Documents and Settings\<username>\Local Settings\Application Data\Apple Computer\iTunes\iTunes.pref
... rename it "iTunes.pref2" and drag it to your desktop.
now try launching itunes again in that user account. that should rebuild your preference files in that account again.
(the itunes setup assistant will run, you'll be asked to agree to the license again, and so forth.)
does it still freeze with new pref files in place?
if it doesn't freeze, and everything's working fine again, would you mind attaching the two preference files that you renamed and dragged to the desktop to an email to this address? (in the email, include the URL to this thread so the person who gets the email has some context.)
send them to this email address
