Please do NOT remove or rename WLDLOG.DLL!!!!
or any other file for that matter
That is the worst you can do!
Removing or renaming that file will cripple your Windows Live Messenger even further!
Yes you might be able to sign in but
you wont be able to add contacts, contact syncronization will be crippled, contacts will dissapear from your list, etc...
By removing or renaming files
you are actually making things worse. It is not because you can sign in that all the problems will be gone. In fact, a lot more invisible problems will crop up!
And later on, when you want to update you will have even more problems.
Again, removing or renaming files like that is the number one cause why people have so much trouble updating or having other kind of problems.
DO NOT ALTER THE MESSENGER FILES LIKE THAT!
-------
In case you have removed or renamed wldlog.dll, please put it back as it was! And because you probably have altered Messenger in some other ways too, you better of completely removing Messenger and all its components and re-install everything from scratch.
Removing or renaming wldlog.dll is NOT the fix for your problems. Instead, check if you have the nVidea Network utility/Firewall or Forceware Network Access Manager and uninstall that. Those components of your nVidea video driver are realy not needed to be installed. They are however one of the problems causing this issue.
Also, ALWAYS consult and read the official support first, like:

^^ = REAL PROPER FIX
Second, if you still have problems, report your problems to Support (instead of trying to fix it on your own by following some bad advise):
