Our tech (he never posts here), was testing the Portable License Utility on one of our computers.. he set it up on 2 computers (comp a & b both with their own license).. then "exported" it from "a" to "b"..(he didn't import it to "b" since it already had one) the problem being, we can't reverse it.. and now comp "a" has a broken license. we have tried a clean reinstall to no avail. I hope someone here has a suggestion or 2.. (FYI, Autodesk help was of no help). TIA.
