Fyi there is no single download for OD 2009, the apps that belong to the suite have individually updated. If you download them the will all be of the latest release. Install them and check version numbers. You should have Bootskin Pro v 1.00.027, Windowblinds 6 v6.30.104, IconPackager 4 v4.10.172, Deskscapes v2.50.067, and Theme Manager v3.00.053.
I'm having the same problem, and the instructions above don't quite make sense. I just renewed my OD subscription and reinstalled Impulse, and I'm still showing the older versions of all applications. Am I supposed to download them again individually? This is not at all clear from within Impulse - despite the fact that I renewed via Impulse.
