Windows 7 - Itunes has stopped working

Question

When I launch Itunes on my Windows 7 laptop it tries to access the Itunes store and says "itunes has stopped working"
it then closes.
I can get it to work by creating a new account on my laptop in Windows 7 and switching ids & then launching Itunes
but I'd rather get my main one working.
Help!

There are preference files at two locations, did you remove both?
Could you confirm that iTunes worked in another account, it is important to know for sure that that true.
Assuming it is, try creating a new empty library as follows:
Hold down the shift key and open iTunes, keep holding the shift key until you are prompted to create a library. Navigate to a location away from Music - for example Documents and create a library. Does iTunes open? This is just a test, so don't worry that it is empty.
*If iTunes opens*, it suggests your old library is damaged and you will need to rebuild your library as show in the troubleshooting method.
Before doing that you will need to use a shift key start to choose your old library. I am not certain if it will work if the library is damaged. If not drag iTunes library.itl out of your iTunes folder to the desk top and copy the iTunes Library.itl that you just created into your iTunes folder so it replaces the one you dragged out. Then use a shift key start to choose it. This is to ensure itunes is pointing at the right place before you re-create your library from the xml file as show in troubleshooting method.
