Did you rename your admin folder perhaps?

In addition, I would double check that you uploaded all of the new IPB files your downloaded from the client area to the right spot.

We would need to look further into this for you, however the access details on file appear to be incorrect or missing. Could you please update these details by visiting your client area, selecting the relevant purchase, then clicking "Review/Update Access Information" under the "Stored Access Information" section. 

We look forward to further assisting you.
