I had trouble logging in, then it told me I was logging in from multiple locations, now I can't.

most likely your connection isn't what it should be, try resetting your modem/router, wait a few minutes, restart it, and than restart your machine.

You also can try a 3rd party viewer , or LL viewer f you'r on a 3rd party already.

 

The message you get is most likely you were logged in, but your viewer didn't really connect fully, so for the servers you were there.

The message that you can't log in for a certain time, is normally only a few minutes, and i never heared it would be the day after as soonest. The time mentioned is used to log your avatar off a sim where it's not responding. That mostly needs just a few minutes.

Often when you try logging in at another region the time mentioned isn't even needed and it will work again.

 

If you keep having trouble, edit your post and add some more usefull infor like your syste specs.

Besides Alwin's answer, it's possible that someone has gotten access to your account.  The most likely scenario for this is that you recently clicked a link that someone gave you in group chat, local chat, or IM, and then logged in to a web page that looked like the Second Life login page.  If you did that, you are the victim of a "phishing" scam.
