[DUPLICATE, LOCKED] DreamWeaver and testing server: ERROR msg.

I have installed the WAMP webserver and try to set up the testing server in DW.
Everything is configured like the Adobe book is telling me, but.... Actually, It should be working now, but I get this error msg:
Dynamicly relates files could not be resolvedbecause the site defenitions is not correct for this server.
Sometimes I get this error to:
This page may have dynamically related files that can only be discovered by the server. 
After the message I have two choices: Discover and Preferences. No of those choices is helping me.
