Unfortunately I don't get that "1.11.0 Some Reassembly Required" page . Let me illustrate the steps and results, just so you are clear
1. In my Account Info=> Your Orders => I see"Kerbal Space Program: Breaking Ground (Direct Download)" with a download button next to it.
2. Once I click the download button, it takes me to "Ready To Download page => in the page I see hyperlinks for the following:
- Breaking Ground Expansion 1.6.0. 1.5.1, etc
3. Just to be clear - I don't see the above "Kerbal Space Program: Some Reassembly Required" screen shot you provided above.
