Can't sign into iTunes account (error 0x80090326)
Please Help!
I logged off iTunes on my PC and can't sign back into my account. I receive the following error "We could not complete your iTunes request. An unknown error occured (error 0x80090326). Now, I can't backup/update/sync anything. iTunes Help > Diagnostics failed secure link to iTunes store. I spoke to level 2 at Apple Care for hours and NOTHING works. Seems like an isolated XP issue. Any solution would be appreciated.
Windows XP
I have tried the following:
installing and reinstalling iTunes
flushing DNS
winsock review and repair
repair of QuickTime and iTunes
ensured iTunes was selected as exception for Windows Firewall
Windows XP patch from 2009 (suggested in previous post)
Also uninstalled anti-virus, turned off firewall. Nothing works
