That's a bit vague and it will be hard to help you on the issue. Did you follow the install guide all the way up to the Postinstallation tasks? This includes bouncing the server etc. and configuring remote compilation etc.
If you've done all that go through the ladbinstall logs and the lafrminstall logs (there should be error logs), see if you see anything unusual or errors and post them here to see if anyone can help.
