MSN and itunes problems

Hi all, new here, have searched around the forums for help, but can’t see anything to help so far.

Installed Comodo the other day, impressed generally as to how secure it is.

Had a problem with my Mozy Back up service, but got that running OK.

There are 2 things I cannot get working:

MSN messenger 7.5 - cannot log in - get an error suggesting I need to check my connection.

iTunes - latest version - can access the program and the store to browse - cannot buy a song though.

Have used application monitor to allow all activies on these programs, to no avail.

Any advice appreciated.

I think I read your other post on this and replied. Do you have svchost blocked by any chance?
