Thank you for the info and advice,
Mike and
Dafydd.
I admit I was so freaked out yesterday morning when PD wouldn't function, that I ran here to the Forum with my question without stopping to do a Search. Now I've done that, and see the previous recent posts about this issue. Well, maybe having the topic brought back up to the top again will help somebody else notice that there is info available.
I see on the download page that there are 6 updates for PD9 which I've never seen before. The third one down is from 2011-03-08, and "Adds support for the latest NVIDIA CUDA setup kit drivers, version 3.2." But that wouldn't do me any good now, since that update is so old now, correct?
On the older posts I've now looked at, I'm not understanding all these references I'm seeing to NVIDIA drivers "versions 301.42 and 306.23." When I rolled back my driver to clear up this problem, the Properties tab calls the driver "8.17.12.6658." It must be listed differently somewhere else, but I don't know where.
I suppose your advice would be for me to sequentially run all 6 of those PD9 updates I'm now seeing, even though I understand they won't fix this incompatibility issue with NVIDIA drivers?
--I let version 10 of PD come and go, and now I've done the same with PD11, because I haven't been very happy with P9 which I find full of awkward quirks and limitations. I haven't wanted to put more money into it, finding it difficult to have faith that a newer version will be something I could be that much happier with. Looks like the current upgrade price would be $60, not much less than I've already paid. I understand that the issue with my video card would be solved at least - I just hesitate to think PD has been transformed into a program I'd actually enjoy using.
I've never changed settings to block auto-updating, I'll go look for that on the computer.
Thanks again for your help. If you have anymore input on things I've mentioned here, it would be appreciated.
