A couple things.
The Mail Lock message means that Pegasus did not shut down properly that last session.
When a session is started a file name MAILBOXP.LCK is created in the Mail folder with a 0 byte size.
It is removed if the program shuts down correctly. It can be left if Pegasus crashes or the system goes down for some reason that doesn't allow the proper closing.
It also happens if you try to open Pegasus twice at same time.
Second thing. New Mail folder is not actually a regular PMM/PMI folder, it is a collection of the CNM messages currently in the MAIL Folder.
The Main Folder is generally the default folder that is created by Pegasus Mail, and default is that messages opened are then moved to it after being opened, But there are options to allow them to stay as CNM files, and also be filtered to other folders or manually moved.
Not aware of option to open main folder on startup? There is a basic option to have it open newmail folder (CNM files), and that is listed at the top of list.
Reinstalling probable wouldn't make any problems.
But would always make a backup of everything in C:\PMAIL to be sure.
Uninstalling and reinstalling could have issues depending on setup.
If you have single user setup or multi-user setup.
In single user setup the Mail and settings are usually in C:\PMAIL\MAIL directory.
In multi-user setup the Mail directories are subdirectories C:\PMAIL\MAIL\ADMIN (example).
If you do install and the C:\PMAIL\MAIL exists it will pick up the settings.
If you remove that directory, and do a clean fresh install it will use the default setup, and you would have to manually copy old files, and if it doesn't agree could have problems.
Again. CNM files are the New Mail messages that have not been moved into a folder.
PMM and the messages in a folder, and the have a matching PMI (Index file of PMM files)
I use preview option, but you may have a different setup.
Good Luck.
