[otrs] Re-register of content_disposition

Hello, I am getting an error when I try to connect to OTRS now. My web browser reports an internal server error, and the apache error log indicates the following: Re-register of content_disposition at D:/OTRS/Perl/site/lib/Apache2/Reload.pm line 158\nCompilation failed in require at D:/OTRS/Perl/site/lib/Apache2/Reload.pm line 158.\n Any ideas what could be causing this? -John
