Sorry, the support process needs to be clarified. The forums aren't 'official' support. That's not to say you won't get a solid answer. But if you want a formally tracked and logged support issue, the route to go is by email: firstname.lastname@example.org
Packager's scripts are designed to rollback on error. You can disable transactions in the options, but this might leave you with a partial sync. I don't recommend it.
OutOfMemoryExceptions are thrown on low disk space as well as a lack of physical memory. Setting the RGTEMP environment variable in a console, then running Packager, can get it to use a bigger hard disk. The default location for temporary storage is in your personal profile (c:\\documents and settings) SET RGTEMP=d:\\temp will get packager to use d:\\temp instead.
Hopefully this sorts the problems for you.
