I have just joined the Adobe support forums for the sole purpose of posting the following. I am posting it here in the hope that someone might know what the error message that I'm getting means and what I should do about it.
My message on the Adobe forum was:-
"In common with a lot of people around the world, I have been unable to get the NIK Silver Efex Pro 2 plug-in to operate effectively.
NIK European support in Hamburg told me that I had a memory issue (which my computer supplier says is nonsense) and to reduce the amount of allocated RAM down to 40% via Elements/Preferences/Performance.
I tried it out of desperation to try and get SEP2 to work better (it didn't work, as expected) but now every time I try to open the Editor in Elements 7 I get a pop up window stating "Runtime Error. The application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for advice."
And all that they tell me is that they no longer support Elements 7 and to use the Adobe forums (do you ever feel you're on one of those treadwheels that you get in a hamsters cage, and you can't get off?).
So, can anyone advise a not-very-technically-minded person what to do about this?
