How do I remove U2 album from my iTunes?

I am unable to get the SOI removal page to work. After asking for my login information, it puts up the login information stickup again and again in an endless loop. I discovered others in the Apple Support Forum have had the same problem but did not discover a remedy.

SOI page link: https://buy.itunes.apple.com/WebObjects/MZFinance.woa/wa/offerOptOut

Thank you
