I cannot use the Updates w/in the main SpyBot interface either due to similar errors.
But I can do updates using the context menu on the Teatimer.
Just right click on the Teatimer and use the Update option available there until this gets fixed... Doing updates this way works fine for me anyway.
In the mean time however due to other issues as well I've gone back to my version 1.3 for now and will have to put up with no more updates for awhile.
