Upgraded to Dopus 10 for nothing...?

Just out of curiosity, I stuck my V8 license code, which I later upgraded to V9 when that was released, into the upgrade page at http://www.gpsoft.com.au/DScripts/upgrade.asp today, wondering what the latest price was to move up from V9 to V10. It promptly told me that "The supplied registration code has already been upgraded to Directory Opus 10 and is no longer valid. Please use the Support link above to retrieve your Directory Opus 10 registration details."

Enticed at the prospect of a freebie, I went to the license retrieval request page to see what would be sent; the license that was sent was headed "Version=9.0".

I take it this is a bug in the upgrade software?

Put in the Opus 9 code, not the Opus 8 code you've already updated.
