Error 500 on install

Hi, Please can someone help me? I'm trying to install CWB but I keep getting a 500 installation error. I've changed permissions on all the files to 777. Plus altered the config.ini.php file as the readme requested and removed the .htaccess file as mentioned in another post. I still have no luck. This is a testing server for me and I would like to test the software in a directory on this server before moving it to the main server. I'm not sure if this has any bearing on the installation problem.

I have ran numberous php scripts on this server before.

This software is just what I've been looking for so I really hope someone can help?

Thanks

500 error is ome missconfiguration, can you send to us FTP info to support at grafxsoftware.com?

You have uploaded files, but wrongly created the chmod for directories.

Admintool and rest of the folder (except publ_images/*, tmp/*, repository/*) should be 755 an the files inside this 755 folders 644.

publ_images/*, tmp/*, repository/* is chmod 777.
