Windows 7: Messenger

Hello.
Well,first off,when I opened messenger and clicked to load the email link off of it,it would just keep loading after the page opened.
I decided to remove windows essentials and reinstall.
Once I did I got the wldlog.dll missing error.
This happened to me before and I fixed it but I forgot how.
Now trying to dump it again its missing from the programs and features now,also from your uninstaller and uninstaller pro?
Any ideas?
Its loaded in my computer I can see the file.
System restore is a no go,some reason I have no old restore points only today?
