Vista - Problem backing up messages in Windows Live Mail

Hello,
I am new to this forum.
I have a problem of backing up emails in my WLM using the export function since I cannot even go into WLM.

I have the typical problem of -
-when I start windows live mail (v2009 final version) it said this :
Windows Live Mail could not be started. The application was unable to open the Windows Live Mail message store. Windows Live Mail was unable to locate it`s message database. If you`ve moved the database filesto a new location.clik OK to resetthe database path to that location. Otherwise, click Cancel to proceed, any existing messages found will be avaible under Orphaned Accounts. (0x000000000, 2)
-if I click OK it said :
Windows Live Mail could not be started. The application was unable to open the Windows Live Mail message store. Your computer may be out of memory or your disk is full. (0x80070002)

Please help me back up my email!

Thank you!

Hello leinaday & welcome to Vista Forums.
If your Anti Virus Program has an email scanning component turn it off to see if that makes a difference.
BTW What Anti Virus are you using?
Another thing to try - right click on your Windows Live Mail shortcut on your Desktop - select "Run as Administrator" - click on "Continue " if User Account Control requests it.
Hope that helps.
