Hi, I wonder if anyone can help? My son like most youngster uses MSN Messenger to communicate but he's not been able to log onto his account for a few days it comes up with the error code 8100030d. I have recently installed an update to my AVG anti virus and now have AVG Internet Security Suite and thought this might be the problem but having followed the instructions for the fire wall etc its still coming up with the same error code. I can log onto my own MSN messenger it just appears to be my son's account that's blocked. I have put this code into Google and came up with a list of instructions like clearing the Contacts cache folder/messenger email address etc but its still not working. Does anyone have any ideas? If I can't get this to work he just left with starting a new account but he's not wanting to that as his contacts are all in his old one.
