Seems like you have used undeploy command.
I will suggest another way.
Stop tomcat
Copy the webapps from the below directory.
Drive \Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\warfiles\webapps
and paste it in
C:\Program Files (x86)\SAP BusinessObjects\tomcat\webapps
Restart tomcat and check after 20 Mins.
