Gill, e-on must be overloaded beyond belief.  I'm coming up on 14 hours myself for a validation on a free upgrade.  I have no clue why a $0.00 upgrade should take so long, but I believe I've read that someone on e-on's end has to manually approve each one.  I know it's hard, but try and be patient.

I dare you, while there is still time, to have a magnificent obsession. --William Danforth
