I've seen other people having problems updating SWB v4.1 and I also had problems trying to update. I would usually receive an error message that read something to the effect "Error: Access violation at xxxxxxxxxx )tried to write to xxxxxxxx, program terminated" After trying to update and receiving the error message I could never start SWB at all after that and would have to uninstall and reinstall v4.1, Just trying different things to see if it would work, I disabled all protection, and then clicked on the update button and it updated the program. Afterwards have to turn protection back on. Have done this twice already and it appears to work. Before updating have 10,000+ items (don't remember how many) in database, 2nd update had 11291 items and now have 11383 items. Haven't tried to update without disabling protection as I'm tired of having to uninstall and reinstall the program just to get it to work.
