I don't know if this might be the cause, but try to move your project to a directory without spaces in it.

Dear friend
Still the error is there, I wonder why it prints out the address of the directory which was on my previouse pc ? (previousley my program was on C:\Documents and Settings\student\Desktop\project incomplete\1-work On\BookTrading\BookTrading )
because the program is already in :C:\testTrading\BookTrading\BookTrading\

C:\testTrading\BookTrading\BookTrading\nbproject\build-impl.xml:209: C:\Documents and Settings\student\Desktop\project  incomplete\1-work On\BookTrading\BookTrading is not a valid directory

any suggestion?

The path must be hard-coded in build-impl.xml. Try to change it.

Dear
im sorry if it's a silly question but Im really new in this one.
the mentioned path address is not exist in build.xml file so I couldn't find where should I change! can you tell me which line I should change?
here is the content of built.xml

<?xml version="1.0" encoding="UTF-8" ?> 
- <!-- 
*** GENERATED FROM project.xml - DO NOT EDIT  ***
***         EDIT ../build.xml INSTEAD         ***

For the purpose of easier reading the script
is divided into following sections:

- initialization
  - compilation
  - jar
  - execution
  - debugging
  - javadoc
  - junit compilation
  - junit execution
  - junit debugging
  - applet
  - cleanup

The top line says "GENERATED FROM project.xml". Did you try to regenerate the files on your machine ?

Also, it seems that it gets a bunch of properties from external properties files : nbproject/project.properties, nbproject/private/private.properties. Check them.

Not "beginning" question. Moving thread.
