Flex coldfusion problem

I deleted some of my WEB-INF files and and then reinstalled coldusion after a CF uninstall. However I am getting the following errors now in Flex builder:

Severity and Description Path Resource Location Creation Time Id
Configuration error encountered on line 1, column 1: 'Premature end of file.' OTT Unknown 1224852579392 19

Severity and Description Path Resource Location Creation Time Id
unable to open 'C:\ColdFusion8\wwwroot\WEB-INF\flex\services-config.xml' ZSystem Unknown 1224849848408 3

Any ideas what has happened?
