getting Error(4) and Error(7) at various point's in the error logs. USB communication seems to be working and firmware upgrade worked. Logs attached any thoughts?

I haven't been around for a few days- sorry. Looking at my ST-Link issue some more I'm beginning to believe it must be an install issue of some sort. The target-settings page starts with a serial number in the serial number box. This box changes to an OLD firmware/ST-LINK already used error. A jpeg of this is attached. I've been reading the um0892 manual, this behavior isn't discussed. Does anyone know this error?

I've been successfully using dfu to do most of what I needed to do. My stlink/v2 trouble may be caused by something related to a test reinstall having an error on this 32 bit PC. I'll try the 64bit machine when I get time.
