just purchased spanner 3>4 upgrade.
in iLok I have “spanner3 bundle” which contains Spanner3 and Spanner. ILM sees all, but won’t go thru w/ the license surrender… ILM throws an error. (My theory: ILM is perhaps trying to surrender the indiv. license, but since it’s in a bundle ILM won’t let it be altered on it’s own…)
I did email support about this issue, but posting in case others have similar.
Thankfully my old license is intact, so I can still use Spanner 3.
