I recently updated to latest iTunes and now my pc freezes. I have a Tosiba 32bit running Windows Vista. Itunes will no longer connect to the store and I get error 42408 when opening ITunes. Please help!!

Question

When I open iTunes I get the error message 42408.
I have googled and tried various solutions including
- uninstalling, downloading and reinstalling. I have done that about 5 times.
- sending the desktop icon to the rubbish bin and recreating a shortcut.
- de-authorising the audible account. My computer goes thru the de- authorisation process and says that the account is deauthorised then when I go to re-authorise under Advanced all that is showing is to de-authorise the account. Weird.
- contacted a tech guy locally and he has no clue. He's thinking it's probably a conflicting software problem. Obviously.
I have to uninstall the iTunes program just so I can use the internet as the new version slows/freezes everything and makes doing anything on my computer ridiculous.
Everything on my computer runs fine when Itunes is uninstalled. Great. not.
I would appreciate some further guidance as unfortunately iTunes seems to have complete control over my life. LOL! Basically if iTunes fails the rest follows... It's a dominoe effect...

Update:
I contacted Apple Support and they agreed to waive the $40.00 tech support charge this one time which was very nice condsidering their update caused major problems with my computer. I realise I don't have to accept the updates but when they are released world wide to the public I do expect them to work relatively smoothly.
To cut a long story short after following the tech support advice and uninstalling and reinstalling itunes 10.5 for the seventh time and more than a week of going in circles and days spent away from my business trying to fix the problem - I gave up.  Because, as a non computer geek,  (no offense - I think cg's are amazing)  what I need is a functioning computer and phone to run my business that can be both relied on - all the time. That is what I paid for and expected when I bought Apples' very smart iPhone - I did not expect to be plagued by an update to a program that causes chaos for over 7 days. (And to be frank I've had problems with iTunes for the whole time I have been using it. From importing cd's to purchasing problems. gah!)
I may be one tiny person in a very large universe but I believe a certain standard can and should be expected when handing over hard earned cash to a company with a good reputation.
I'm very disappointed with Apple.
Unfortunatley they have lost a customer...
This is how I fixed the problem:
Yesterday I bought a new smartphone - the Samsung Galaxy phone uses the Android Market and the Kies program. The phone is as good as if not better than the iPhone. The Kies program runs very smoothly on my computer. Downloading Apps is a breeze. My new phone is about the same size as the iPhone and a tad lighter.
Problem solved!
As a side note - I will now save about $250.00 per year on my new prepaid phone plan with Boost compared to staying with my previous post-paid plan. I also get unlimited standard national calls in Australia plus unlimited texting too! Not bad for $40.00 a month.
While this solution worked for me it may not suit everybody.
