Giving up... for now

Wishgranter- I cleaned the inside of laptop not too long ago when I upgraded ram so i don’t think that is an issue.

Out of interest I re-ran a little project that I had successfully processed a couple of months ago (so a previous build of RC).
Only 105 images, small flight over a couple of stockpiles- fantastic output.

Guess what… it failed this time! Same thing “Unknown error, CUDA error : 30 :unknown error”
There has got to be something going on in the latest build that has changed and it doesn’t like my hardware or OS?

Can someone reset my activation period so I can try this on same machine but with windows 10?
