The third party tool is probably attempting to use an invalid handle. Most likely, the handle was valid but is now closed (or is set to INVALID_HANDLE_VALUE). Note well (N.B.): INVALID_HANDLE_VALUE is different than NULL, and its easy to mix the two up. For example, some functions return NULL on failure, others return INVALID_HANDLE_VALUE. It depends on the context/object, and you have to pay attention to details on the Win32 call.
