error in Zend loadClass

unknown error

[merijnvw]

On my own server this works: I require_once the zend loader.php, and then load some classes using for instance:

Zend_Loader::loadClass('Zend_Gdata');

But on an IIS server it doesn't work, it gets a fatal error after the first loadClass. I have no idea what causes this, and the IIS error page is vague about it.
Any idea what I can do about it? thanks.

What is the error?

Error Code0x00000000

Most likely causes:

* IIS received the request; however, an internal error occurred during the processing of the request. The root cause of this error depends on which module handles the request and what was happening in the worker process when this error occurred.
* IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly.
* IIS was not able to process configuration for the Web site or application.
* The authenticated user does not have permission to use this DLL.
* The request is mapped to a managed handler but the .NET Extensibility Feature is not installed.

Well that seems to have frightened potential answerers off
if you are one of those, please know that even some suggestions may help me because you are probably smarter than me

RESOLVED
it was an include_path issue...
