okay so I signed out of msn a while ago, then came back on and couldn't log in. it said my password was incorrect and so I went onto hotmail to change it and it appeared to work?

then when I use actual msn (not hotmail) it won't work, and it won't work on ebuddy either.

I'm so annoyed right now. what can I do to make it work again?

We are not Microsoft, so we can't do anything about it.
You need to contact Microsoft for this.
In Hotmail (and any other MS prodict for that matter) there is a contact form and/or link to their Help Center and forums where you can explain your problem.
You can also find the same help resources from Microsoft's Help & Support Center.
