First, what version of WEmail are you using?
The current version is: Version 2012 (Build 16.4.3505.0912)
I recommend that people use the 2012 version due to stability.
Second, have you tried to repair it?
exit out of WEmail
WinKey+R -> brings up the run dialog box. Type wlarp.exe in it, answer yes to the uac prompt, then select repair all WE programs.
If that doesn't help, try a reboot.
If that doesn't help....
exit out of WEmail, if running
Duplicate your working WEmail configuration is to copy the .oeaccount file to a flash drive
on the new machine, Create a temporary folder in the WEmail folder
put the .oeaccount file in that folder
To make the example easier, I'm going to use the following names
Bill - user name
RRmail - WEmail account name for roadrunner
account{xxxxxxxxx-XXXX-xxxx-XXXX-xxxxxxxxxxxx}.oeaccount - as the account file name
tmpoem - temporary WEmail folder name
Of course your information will be different, make the appropriate substitutions
On your desktop, navigate to your Windows Live Mail folder
--> Note: you might have to change the folder options to see hidden files
C:\Users\Bill\AppData\Local\Microsoft\Windows Live Mail\RRmail
copy the .oeaccount file to a flash drive (should only be one account file in the folder)
On your new machine
navigate to your WEmail folder
C:\Users\Bill\AppData\Local\Microsoft\Windows Live Mail\RRmail
--> assuming the same names were used
create a new folder tmpoem
copy the .oeaccount file from teh flash drive to this new folder
Fire up WEmail. You should see a "new" account in the left pane.
I have limited connectivity, so I mifght not be very responsive. Saw your post and thought I'd offer some suggestions. I can't guarantee that I can get on to follow up though.
Perhaps another member can help if you get stuck or have more questions.
