Try removing the environment files before you upgrade (or after if you didn't save the old file). When I released that version of NOID I have since regretted leaving in code that created a stub environment (that actually isn't used by NOID) because it just creates upgrade problems that I never figured out properly. If all else fails and you're just using NOID to mint (eg, no binding), it's quite easy to start a new minter from scratch and mint until you see the last id you minted prior to conversion. The order of minting is deterministic, so in the end you'll have a new minter that's in the same "state" as the old minter (again, provided you haven't been doing holds and binds -- that's more complicated). -John --- On Tue, 14 Feb 2012, Joshua Gomez wrote: > Thanks John!
