Problems since update

Help needed. We just spent 54 minutes cutting a full sheet of intricate ornaments. Unfortunately we experienced about 3 to 4 mm of drift south in the Y access. This has never happened before and we just installed the new upgrade 2 days ago. Is this a new software bug? how do we fix this? Do we need to reinstall the old software? THANKS
