Lost old calander creating a new one

WIN XP/PRO SP1 - WORD PERFECT OFFICE 2002 - COREL CENTRAL 10
I wanted to make a new calendar to track a project (I would have my normal calendar and I would have a second calendar to track the project.) I did file|new within calendar, built my new calendar and Corel gave me that nice msg stating there was an unexpected error and the prog must terminate. (Registry key was missing hkey_local_machine/software/Corel/<I don’t remember the rest>.) After I restarted the calendar, I had the new calendar but my normal one was gone.

When I file|open a calendar, the old calendar name is not listed - if I could get it in the menu, I would probably be ok. Any ideas on how to get the old calendar back? Or even what files to restore if I restored from an old backup?

The data is there, i just cannot get to it:
D:\DATA FOLDERS\Corel\WordPerfect\Docs\CCWin10\Calendar contains two folders: 1 for the newly created calendar and 1 for the original calendar and both folders contain the same files (dif size date ) except that the old calendar folder contains paradox.lck and pdoxusrs.lck both of which have a timestamp of today, so I probably created them in my attempts to gain access to the calendar.

I have no problem editing the Registery.
Thanks in advance

FYI: Using Regedit, I replaced the new calendar name with my old one, was able to retrieve the old one, and then created the new one again (and had no registry errors as before) and everything works fine.
