After opening the project you wish to revert, on the Tools menu, click Revert to a Previous Build....
This allows you to load file choices and project options used in a previous build.
Choosing one of the folders named <project name_date> allows BuildPlus to find the <project_name>.nod file within that folder, and revert the project to file choices and project options from that date.
If no .nod files are found, try a different folder or contact GMCL for assistance.
If multiple .nod files are found, but none are named <project_name>.nod, Contact GMCL for assistance.
