Internal Server Error

Hi,
i've installed the latest stable release of Bitweaver but i've got a problem. I got this error from my server:

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, webmaster@******* and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Is there anybody who has got any experience with this error and could help me?

Thanks

Jeroen Verheye
