Running tests made using previous versions of UFT can fail because of an update in the description properties used to identify objects. Using the Object Spy (and in the Object Repository), check the offending test object's *name* property. Make sure the *name* property in the Object Repository matches the value of the name property in your Object Spy and update in the OR if needed. Also, for UI Automation objects, always use the *name* property for object identification, as this property allows UFT to find the object the fastest during your test runs.
