Running iTunes as Administrator fixed "iTunes has stopped working" error.
I have this problem with iTunes. Whenever I try to access the iTunes store, I get the Windows "iTunes has stopped working and needs to close" error. I am running Windows 8 64-bit.
If I run iTunes as Administrator by right clicking the iTunes icon and clicking "run as Administrator" I no longer experience the issue.
I'm running the latest iTunes version as of 10/11/2013.
