Hi,
two things to mention on this:
1) Right, the token is unresolved in the package details on the package server but is still resolved while trying to download. Could be verified in the logs of the package server.
2) Is there an existing deployment share on your package server? I have no upgrades site server here, but a new one and the deployment share doesn't exist anymore, neither on the smp nor on the siteserver.
Did you queried the log on the package server for any errors? On windows 2008 you find here: C:\ProgramData\Symantec\Symantec Agent\Logs
For the second problem: While editing the package, open please the log viewer of smp and verify if there is any error written down while saving the package.
Regards
