WELL, I HOPE THIS WILL HELP YOU GUYS LIKE IT HELPED ME

Recently the windows live desktop beta showed a message at startup that an
unexpected errror occured and needed to close at once. I found a fix in the
live mail desktop section that is renaming the windows live contacts folder.
It worked fine as the problem as I can understand was something with a
corrupted contact list.

But this solution did not work for live messenger beta?

Is there something in the beta versions that are corrupting the contact list?

Thanks to all of you who are trying to give solution,
but none of them works. The only way to get messenger work is waiting for
the update which can be posted unfortunately maybe after several months ,
because since october nothing was done. the main reason of the problem was
deleting-blocking groups. Others who had deleted some folders of msn
contacts in system
and after messenger worked had another type of temporarily problem.

Still waiting for live team, hoping the will solve soon.

I have just installed the new beta release of the live products, but for a
change the live messenger is not signing in again.

Now it's giving temporary error code 8100030d. Any help???

I also found some suggestions that say to load dll extensions.
A question regarding this - does messenger need rundll 32 to work and show
it be allowed access to the internet?

Thanks

Ok, finally I found the what was causing the problem with the signing in.
Avg suite was preventing messenger from going through the internet.

For those who have avg suite - go to web shield - instant messaging and
remove msn protection.

You will be able to sign in then.

Daniel this was very very helpful I wish things were able to be compatible in
this day and age but sadly they aren't I appreciate it
