Error -9808

The top 4 fixes to itunes error 9808 seem to be

1) Go to Start > Control Panel > Internet Options > Advanced, make sure that SSL 3.0 is checked and TLS 1.0 is checked. Also under Security make sure that the “Check for server certificate revocation (requires restart)” is unchecked. Then click ok and fire up iTunes.


2) Time or time zone not correct on your PC.


3) The culprit was Norton. Ggo to Norton’s Personal Firewall and add the program “iTunes Helper.exe” and set the option to “Allowed” (”iTunes.exe should already be in the Allowed category.)


4) Delete or cut the preferences.xml file which contains your iTunes preferences.
Close iTunes if you have it open right now. Then go to C:/Documents and Settings/username/Local Settings/Application Data/Apple Computer/iTunes. Then go to C:/Documents and Settings/username/Application Data/Apple Computer/iTunes and delete or move the preferences.xml file. For Mac users, there is only one file you must delete or move a to a new location and is located at User > Library > Preferences > com.apple.itunes.plist. Restart iTunes and it will recreate those two (or one) files with the default settings. You';; need to set your preferences back to what they were and then connect to the iTunes store.

Well i solved it on another way.

In Internet explorer options / contebt / certificates
i search for the certificates having the enddate corresponding to the date i began to have problems. i deleted those 2 certificates and started the communication with iTunes again...
new certificates were downloaded and it works fine now.
perhaps it can help others.

Oh,that's a good tip!
Kinda like the #1 I posted but it gets new ones.
