mailrt2 dll error in Windows Live Mail

:cry
I am trying to open Windows Live Mail and getting the following error message:
C:\Program Files (x86)\Windows Live\Mail\MAILRT2.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.

I haven't been too successful finding a definitive answer on the topic as of yet. Any help would be appreciated. I don't want to reinstall the program if I don't have to so just want to see if anyone has any answers. Thank you!
