dont know why people think uninstalling and reinstalling is the answer. If you havent ran updater in awhile, run it to see if you have the latest version of BuildOS or not. if so, check the
Titan_WM6.1_20273 Selections.txt file in the Projects folder on this path-
C:\ProgramFiles\PPCkitchen.org\BuildOS\Projects
I'm not sure its been updated yet to work with the new BuildOS however, so you might get a kitchen_config error then. on the line in that selections that says OptionalModuleDir=kitchens\PPCGeeks_OEM.rar:, change the PPCGeeks to PPCkitchen now and be sure you have downloaded that rar recently.
