Newbie mistake here. After starting milestone test run I became more familiar with how to use Configurations.
So I had a Test Plan using a couple of configuration items. Today I realized I should have added a 3rd (OEM) configuration for completeness. BUT this was on a Test Plan that was completed.
Not realizing what this would do I added the 3rd config item and now all 274 results are gone (dumb mistake).
Is there any way to recover them?
