Yes, well, I downloaded a lot which has me rather worried. I've checked, and all EPs and CC are secure and in the right place. And yet, I have this:
I'm not so much concerned with fixing it (I can live without using that lot) as I am with why it is happening, is it a warning sign of BFBVFS, and how I might prevent it in future lots. And yes, I have tried taking out the lot and reinstalling it.
