Sorted!
Not sure who to thank, so I'll thank everybody, on general principles
However-
StaceyF, I downloaded and installed as per your link. Many thanks!
SD- Also blew the dust off the folder containing IE, loaded the plugin from the Adobe site using that.
I don't know which "fix" fixed me, but my USD 45.- software now works (although it works out cheaper here in EURoland
)
Thanks all!
