When I try to login to my AOL email, I get an Alert message that says my account has been block due to suspicious activity. I have no idea what that means! I haven't done anything unless someone hacked it and I have emails I saved for a reason an need them. As well as emails from sites about account information like Facebook. I really need access to that email.

Change all your passwords for all your online accounts. After you have changed all your passwords cont act AOL help (http://help.aol.com/help/microsites/search.do?cmd=displayKC&docType=kc&externalId=217480) about resetting you password and getting your account back up.
Remember to use hard passwords of at least 8 characters win upper and lower case characters as well ans numbers and special characters the !@#$% type stuff
