Finally got Adobe ACR 8.2 to load properly.
I finally got my standalone CS6 to update to the new ACR 8.2. I had to download and run the CC Adobe Application Manager, which took quite a while, hit update, and it is all good.
I haven't been able to get my laptop's CS6 to update properly for ages. I think it must be a bottleneck with CC vs. my "old" standalone CS6.
Hope this helps anyone with the same headache.
Many thanks to those who helped me work though this issue; this is one of the best forums on DPreview!
