Google 1, Yahoo 0

I fixed it! Have my editing software running on the new memory card. Too pooped (9 hrs working at this) to explain, will tomorrow, except to say this ... I suspected someone had had this problem before, of course, and a solution was on the net. I'd been searching "Adobe 0x00000018" but getting nowhere -- in Yahoo search engine, which I habitually use. As a last resort, I did the same search on Google ... and there, at the very top of the page, was reference to someone with the same problem, and in a long discussion at a forum, after trying a zillion things, he tried something that worked. I tried the same thing -- and it worked for me, too! I'll give details tomorrow, it's an interesting thing to know.
