deleted Hl2 prefab.

[FrobTheBuildeer]

i accidentally overwrote a default HL2 prefab that was a vital part of a tutorial I was following, it is the button_keypad. is there any way i can retrieve this prefab file and get it back?

Refresh the SDK. That should reset all of the Source SDK's files that are in sourcesdk and sourcesdk_content
