oracle wont start – http://localhost:8080/apex wont open

This is a new problem with vista. My computer automatically installed new vista security updates and then restarted, now I cannot open the oracle homepage, which doesnt help me considering I have an assignment due on tuesday. I am working on a solution to this, the errors I have gotten are: is not set up to establish a connection with port 8080

and access denied.

 I am sure this is because of the new security updates, if anyone has a way to fix this HELP
