can not access reports

This was working before but all of a sudden when I try to access reports server
http://myserver/reports/
I get the following error:
Access to the path "C:\Program Files\Microsoft SQL Server\MSSQL\Reporting
Services\ReportManager\global.asax" is denied.
Please help..Looks like permissions or users have changed. The Web service user needs
access to this file. Make sure the Web service identity user has
permissions to that file.
