I use A9cad a free program to draw designs , mostly residential homes. My problem was on my last save of a 40 hour project, an error message appeared. "object has disconnected from client" and the program closed. when i re opened it, the entire drawing was gone and all of my parameters and selections had been changed back to default settings. I have used this program for many years and never had this happen before. Is there any way to recovery the file. I know the exact moment the file was modified. have done a system restore in hopes of correcting. nothing works. any advice would greatly be appreciated. the project was 95 % complete and will be a bummer to re draw
thanks
