I have gotten that message before at least 4 times that I can remember and it seems to be a glitch and then I can't see the shop in my list. It terrified me the first time. I log out and log back in and then the shop is there and I can finish the report. It has never affected my ability to finish the report and the reports have all been accepted, so it does not appear to be more than a random annoying thing. Try exiting and logging back in. This worked for the each time it happened.
I have my fingers crossed for you. Come back and let us know.
