I click on "new", enter the user info, and click okay, but get an error noise, and the name is not added.

Sounds like either a bad path or yuo do not have the rights to the directory on the system.  Try using c:\pmail for the program and c:\pmail\mail when asked for the location of the mailbox.

FWiW, if this is Vista you should always make sure you mention you are using Vista when asking any type of computer question.

Hello all; I've recently booted a new pyooter, and am loading programs. I installed a fresh Pegasus v4.4 email client, but can't get past the "create Initial users" window. I click on "new", enter the user info, and click okay, but get an error noise, and the name is not added. I can't do anything, and have (on an external drive, copied from the old pyooter) all of my prior pegasus files, addresses, etc, but until I can get the new one up and running, I'm stuck. Help!! Any suggestions??  Thank you!
