ITunes won't open but there's no error message...

Question

...it just won't open.
I just updated to iTunes 7 because of an issue I'm trying to correct with my iPod. I believe I've had this problem with iTunes 7 before, and the last time I ended up reverting to iTunes 6.
When I manage to successfully install iTunes 7, I click on the desktop icon to open it and it looks like it's about to load, but then nothing happens. So I try opening it from the start ment and still nothing. Then I try opening it by trying to play an mp3 through it, and still nothing.
I really hope someone can help me with this, because if I end up needing a new iPod I'm gonna need the newest iTunes for it, I'm sure.

Help! This is happening to me too, and I can't find the fix, if there is one. I just downloaded the newest update (wish I hadn't). It took a few tries to open it, but it worked. The second time, it didn't open. NO error message. I've tried every way of opening a program, and nothing happens.
(1) do you have Norton Internet Security 2005 installed on the PC?
NO NORTON INTERNET SECURITY 2006
(2) try launching your QuickTime. does it:
(a) launch perfectly fine?
(b) fail to launch with an error message? (if so, what does it say?)
(c) exhibit other peculiar behavior? (if so, could you describe it for us?)
IT SAYS IT IS LOADING... FOR OVER 15 MINUTES
(3) reboot the PC. bring up your Task Manager, and click on the "Processes" tab. now try to launch itunes again.
does an "itunes.exe" process appear in the Processes tab? if so, does it persist in there or does it disappear after a few seconds?
ITUNES.EXE DOES SHOW UP IN THE PROCESSES TAB AND STAYS THERE
THE ONLY OTHER ODD THING IN THE PAST YEAR, IS THAT 2 WEEKS AGO, A WINDOW CAME UP ASKING IF I WANTED TO RECONFIGURE WHAT STARTS WHEN I START WINDOWS. I CHOSE THE WRONG THING BECAUSE NOW THERE ARE TONS OF EXTRANEOUS PROGRAMS RUNNING ON MY COMPUTER.
HELP!!??!!
