how can these files be resurrected?
I have a second machine and it is not a problem to load the same file and open it. Is it just a question of reinstalling sketchup?
Thank you for your help and interest in my plight, you have been very helpful.
The graphics card is apart of a newish Dell laptop, which does have some text sizing issues. but it is a good work horse.
some of the models are 140mb cities with boats and stuff. handled it all very well untill last week with the Lightup extension and the soap bubble extension.
Did all you suggested, must have been thinking concurrently.
