Error saving package to msdb (IA64 - April CTP)

When attempting to save a copy of my .dtsx package (from BI Dev Studio), I get the following error. Any one have any ideas? - note: This is an IA64 machine running W2k3 Server (SP1). If I select * from msdb.dbo.sysdtspackages90 I get no rows.

Thanks!

Additional Info: I've been checking the public newsgroups and this error appears with SQL2000, too. Most proposed solutions relate to certificates being installed. I've checked the various places (xyz\certificates\personal) where the problem certificates might be and have found none, so uninstalling these certificates is not a solution.

Any other ideas? Any would be appreciated!

Thanks!|||I just blogged about this:

Basically, with earlier CTP releases you have two options, supply a self signed cert to the server or upgrade to the June CTP.
Thanks,
