Please try to disable your virus scanner. The latest update only fixed a single bug, certainly nothing that could potentially lead to vorpX not working anymore. Your description sounds a lot like a conflict with some other software.
Some overzelaous AV scanners however “detect” each new vorpX as potentially malicious since it hooks into otherf programs. If you use anything else, I would highly suggest to switch to Windows Defender, which provides good protection without being as annoying as some other scanners.
