Now that I am done with my project, I will try uninstall and reinstall
I will check the links you provided for patches
After it shut down a couple of times, I took it upon myself to discontinue running any other programs. The only active program was PD7.
And I also got into the habit of saving my work progress about every five minutes, because I never knew when it was going to shut down. I also saved the work to two independent files.
Plenty of HDD space. I'm working with 2 120Gb drives. My PD files were not even 5Mb in size.
Thank you for your assistance. Also apologize for double-posting my last query that you replied to that wasted your time. Will not do so in the future.
Will try the above link / patch suggestions and update on solution.
