Since downloading Itunes 10.7,the audio has deteriorated,with both missing and stuttering of music.
Itunes 9.2 was not problematic,as far as audio was concerned.
Any suggestions?

Update:
I re-downloaded iTunes completely and learned that iTunes will keep ALL of your content, music, pictures and information that you had on your previous iTunes and transfers it to whatever new installation of itself you put on your computer. In this process it also deletes whatever version you had previously, along with any shortcuts, and replaces them with the newest version. (Many people, when searching online, said that Apple had no official fix or solution to the iTunes updating issues, but I think the way iTunes replaces itself like this was made in case of such event, which would explain why I couldnt find any official processes to fix this).
All you need to do is go under iTunes on Apple's site and download it (even if you already have it) and it will just replace your old version. You will have to go through all of the downloading process (wizard) but it will be well worth it.
I suggest this to ANY and ALL who are having issues with updating thier iTunes or downoading the update, especially those who have updated their iPhones to iOS6 through their phone and not computer. I am pretty sure it will work on other versions of Windows or on a Mac, and hope this will help anyone else who is having this issue.
