The service pack error is caused when you let it pick the folder to install it to, click the browse button & find the poser folder yourself (it's the same one the updater finds but hates). When was the last time you defragged your harddrive? Poser does like to have plenty of room when running to spread itself out & if your harddrive looks like my sock drawer ( stuff everywhere) then it'll kick up a fuss. Have you used CorrectReference recently? using it to sort out the texture references in poser will speed it up nicely too.
