Home sharing login

i'm having the same problem, i just signed up to this group, and i had to use the username & password in order to log in & join.
i am using Windows 7 (64bit) and i've installed iTunes 9 (64bit). although i've tried the same with my PC @ work (Vista, 32bit) and i get the same message:"Home sharing could not be activeated becuase the account or password was incorrect."

Try clicking on iTunes Store within iTunes. On the upper right click Sign In. From the Sign in Box there is a button to create iTunes Store account.

Maybe it is not a username or password error at at all. Especially after you tried to create a new account as I listed above and it still does not work.

Maybe it is security software or firewall blocking and just returns this as the error. Anyone running CA Internet Suite?

I think I found the issue. I recently purchased a new MacBook Air and I wanted to share some of my favorite songs over to it. So I set up home sharing on my MacBook Air and it worked nicely. Then I attempted to set it up on my iMac. Big problem. It kept saying the username/password was incorrect. I pulled my hair out for a couple of hours then started troubleshooting. Fist removing iTunes PLISTS then making new iTunes libraries, all to no success. When I made a new User on my mac and it worked that told me the issue is User account related (On the computer of course). Finally found a folder called iTunes sitting in the user library and decided to pull it. VOILA! Issue resolved!!!

In case you are wondering, heres the path: Macintosh HD/Users/(your user account name)/Library/iTunes

Keep in mind that there is iTunes plug ins and mobile backups in there so be mindful that by moving this folder can cause you some other issues/data loss. AS ALWAYS make sure you are backed up before attempted anything like this!!!!!

GOOD LUCK!

The fix for me was to log the second computer into iTunes with the account of the first computer.
