How to recover an application from Server - Very Urgent!

Hello,

I have accidently deleted an important DynPro application I've created from the Netweaver Developer studio.

When I search it's name at the server I see many many ear (and wda) files with the name temp<MyApp_Name> from different dates, I guess each deployment is creating such file. How can I recover my application back to the Netweaver Developer Studio from these ear files?
