APEX

Hi,
For some reason, I get the following message when trying to connect to APEX:
"Service Temporarily Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later."

I'm working on local with Windows XP and 10gR2 Database and connecting through http://localhost:7777/pls/apex

I can enter http://localhost:7777/ because de HTTP_Server is up and status Alive in OPMNCTL

I've been working on it for some time now without problems. I think my IP changed since last time I connected, apart from that I can't think of anything else that is different. I also think it's this because when I took my PC some place else and connected it, this also happened.

I've tryed to find where that IP might be hard-coded but No way. Windows Hosts has my loopback IP (10.10.10.10) as localhost, the DADS file contains the right connection string and logs say there's no listener, but it is up and running, DB works ok.

I really don't know what else to try, hope to find some help. Thank you.
