Now, in a case where you simply cannot open an .lbk file for whatever reason, it does not mean that you have completely lost everything. You will however need to spend a little time recovering your plotmaker file. Two things to do before you undergo this process, are:
- Restart you computer and see if that helped
- Try opening your "PlotMaker Layout Book Backup File" (a duplicate of your main plotmaker file)
start a new/blank layout book and import views from your corrupted .lbk file using the import command. You may have to re-link view sets to the corresponding .pln file but its better than nothing and starting from scratch.
