can not start Apache Directory Server as service

Hi community,

I installed the Apache Directory Server 1.5.5, but after the installation i can not start the ApacheDS as a service in Windows. Below you can find the error message from the wrapper.log;

ERROR [org.apache.directory.daemon.Bootstrapper] - Failed on null.init(InstallationLayout, String[])
INFO | jvm 1 | 2009/09/03 09:43:43 | org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'directoryService' defined in URL file:/C:/Program%20Files/Apache%20Directory%20Server/instances/default/conf/server.xml: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.apache.directory.server.core.DefaultDirectoryService]: Constructor threw exception; nested exception is java.lang.IllegalStateException: Something has got to be severely wrong with the core packaging
INFO | jvm 1 |
2009/09/03 09:43:43 | or the build to have resulted in this exception.

i have no idea what causes this exception but i tried to install it to another computer and got the same error message. My OS is Xp and other computer's is Vista, but i couldnot start it in both computers. But interesting thing is, i didn't see anything about it in forums, am i the first one having this problem or do i miss something?

thanks,

Yakup
