Sorry for taking so long getting back, but I thought you'd like to know that replacing V09 with a full D/L of V10 worked perfectly, the BR save did the trick. I've no idea what happened to my save, but, oh well. One of the reasons I was so long replying, was because I D/Led both packs which took a while, then extracting, etc, testing the save, which as I say went great, but the real delay was because of the updater, I thought I'd run it, & it showed a 36Gb D/L which I triggered thinking I'd retest the save again afterwards, that D/L ended up run ning 3 times longer than the original game D/L, so I went to bed. When I checked today, everything ran fine, so thanks again for the suggestion.
P.S. Sorry for rambling on.
