Only choose one item at a time in the updater. The updater is buggy right now.
You also will not need the 3.35 kitchen unless you want to build a WM6 ROM.
5060 is the latest WM6.1 kitchen.
If you still would like the 3.35 kitchen, the rar and selections.txt can be found at
http://ppckitchen.org/downloads
The selections.txt goes in program files\ppckitchen.org\projects and the rar goes in the kitchens folder.
