ITunes crashing when typing in iTunes Store

Question

Hi,
I recently just got iTunes 10.1.1 on my laptop and when I try to type anything in the iTunes Store (such as signing in and entering a redeem code or just pressing a button on the home page), iTunes crashes with no error message except for the "Windows is checking for a solution" box. Local operations such as syncing and listening to music works and it is only typing in the Store that causes the crashing. I have tried a reinstall but the same problem keeps happening. Any ideas on what might be causing it?

No worries about any delay.
Fault Module Name: JavaScriptCore.dll
Fault Module Version: 5.33.19.1
If we take that at face value, you're having troubles with your Apple Application Support. (iTunes needs a properly functioning Apple Application Support in order to work correctly.)
So let's first try uninstalling/reinstalling both Apple Application Support and iTunes, taking a few other explicit precautions just in case. Best to print off a copy of these instructions, because at one stage of proceedings you won't be able to use a web browser.
Preliminaries
Download and save a fresh copy of the iTunesSetup.exe (installer file) to your Hard drive. (Don't run the install on line, and don't start the uninstall just yet.)
http://www.apple.com/itunes/download/
Quit any recent version of the QuickTime Player, Safari for Windows and/or the MobileMe Control Panel for Windows if you have them installed and open. (They all use Apple Application Support, and may interfere with the AAS uninstall if they are open.)
*Uninstall Phase*
Head into your "Uninstall a program" control panel. Uninstall iTunes. Uninstall Apple Application Support.
(From this point onwards, recent versions of QuickTime, safari and the MobileMe Control panel will not launch, until we get AAS reinstalled by reinstalling iTunes.)
Next we'll remove any left-over program files and folders.
In "Computer" open "Local Disk C:" (or whichever drive you have your program files installed on).
Open the "Program Files" folder.
Right-click on the "iTunes" folder (if it still exists) and select "Delete".
Open the "Common Files" folder.
Open the "Apple" folder.
Right-click on the "Apple Application Support" folder (if it still exists) and select "Delete".
Empty your Recycle Bin.
*Reinstall Phase*
Restart the PC. After the PC restarts do not open any applications. Disconnect from your network and/or the internet. Now switch off all your security software (firewall, antivirus, antispyware).
Now start the reinstall by doubleclicking the iTunesSetup.exe file you downloaded earlier. (This should also reinstall Apple Application Support.)
Reenable all security software prior to reconnecting to your network and/or the internet.
Did the reinstall seem to go through properly? If so, can you type in the store without the crash now?
