I have a Sony Reader and like most new devices, it tends to lock up occasionally so it needs to be reset, removing all information from it, including DE activations.
I have been able to reauthorize till now with no problems. But today I am on number 5 activation and it won't do it. I get the E_ACT_TOO_MANY_ACTIVATIONS error message.

I have called Technical support in UK and they have no idea how to resolve this. A case has been opened #180428658

Quite frankly this is not good enough. I now have a non authorized device and lots of DE books I paid for but now can't read !!! There has to be a way to solve this, come on, it must be easy enough. Why limit the number of authorizations? People need to reset devices so this will always be an issue unless you resolve it quickly.

I now refuse to buy any more DE books, why bother if your DE locks me out fo them? Money down the drain, so I will not purchase any more DE books.

I have seen the 'workaround' where you create a new account on XP, but I don;t see how this is good enough. Plus all my books are stored on my normal account, so how would I get this to work? I guess you'd want me to transfer all my books to the new user account on XP. This really is not a solution at all. I need to use my usual XP account, I have everything stored on there.

This matter needs to be urgently addressed. I have paid good money to buy eBooks for my Sony Reader and now I can't read them due to a software glitch in DE........and you have no solution. I can see this issue was raised back in August, yet you STILL have no solution!? Not good at all.

I will not be wasting any more money on DE books until you can solve this and get it to stay solved.

I sincerely hope that you can at least try and resolve this issue urgently, please
