Packages unavailable for selection as data source

[Cognos_Chris]

Hi, hopefully someone can help with this as it's driving me mad!

I've already got transformer install on the application server and cubes build fine as expected.

I have now tried to install transformer on another server and I believe that it is setup correctly. I can open the existing pyj files fine, however when I try add a data source, some of the packages are missing. I'm logging in with the same Cognos details (which is an admin user) and running transformer as an administrator. Any ideas?

Cheers,

Chris
