I have been having the same issue and so are a couple of other people.
First it seems to be ok in Internet explorer.
It may be related to a firefox update as I spent ages trying to get in - I have now managed to
In firefox I went to tools - options - privacy and remove individual cookies and removed the cookie for godigitalscrapbooking.com. When you go back to the site you may get a warning saying cookies not detected - just ignore it and go next and hopefully all will be good.
If not try Internet explorer.
I have been having heaps of trouble just getting into the store or forum though - we must be popular today lol. Actually took me an hour to post this the form kept timing out so i removed cookie again and here I am.
