How do I add names to an existing 'Category' (Group Name) using Windows Live Mail?

For the past couple years on my Dell laptop, I have used Windows Live Mail to organise my e-mail accounts. One from Hotmail and another  account. However, last week for some unknown reason, I was unable to send or forward any e-mails from the account, even though I was receiving mail in both accounts.  Today, I cannot even access it at all. I keep getting a message up saying that C:\Windows\system32\MSVCR110.dll is either not designed to run on Windows or it contains an error.

I have tried unsucessfully to download the file from various websites offering downloads, but nothing seems to work.  I can still receive and send e-mails using my Hotmail account, but I had numerous folders on my Live Mail system which I can no longer access.  Any ideas how to reinstall this damn file or just to get access to my folders?

heg jeg får ikke logget med inn på windows live id??
I use an internet service provider (Cox Communications) for my email and the Windows 8 Windows Live Mail client (just upgraded from Windows XP and Outlook Express).   I have many duplicates in Contacts, spent hours deleting and when I logged back in, they had all returned.  I don't use Hotmail nor do I want to.  I actually keep my 'good' list of contacts in gmail as that seems to be the only thing I can figure out and which seems to work.   But I'd like to be able to delete the 5000 contacts in the Windows Live Mail Contact folder and start over.  Any solution to this?
I am currently using Windows Live Mail. My messages are marked as "sent" but no one is receiving them. Can you help me?
As above in that the "sent section" of Windows Live Mail shows empty when I have sent mail.
I have set up three different accounts on Windows live mail to email accounts using POP servers.  On all three accounts, the incoming mail never arrives in Live mail and it is deleted from the host account.  Anyone know how to fix this?  Windows Live is set to leave mail on the server.

the problem started today i signed in to messenger and clicked on the "you have 3 new emails" and instead of taking me right to me email inbox it takes me to the windows live homepage.  this is new to me and i don't much like it.  i am running xp, messanger live version 14.0.8.117.416.  i hope it is a problem with an easy fix.  i can still click on the link in the windows live webpage but it the link should take me to my inbox.  thank you for you help and hope to hear back soon.
